The sterilizing and deodorizing agents target bacteria, odors, toxic substances, etc. and are made from silver as metal particles and titanium dioxide as ceramic particles by (1) thermal bonding or (2) pressure bonding or (3) thermal/pressure bonding and mixing the resultant with hydroxyapatite as an adsorptive material. The agent can be mixed with ink, bonding agents and paints and applied to a variety of substrates.

1. A sterilizing agent having a sterilizing effect without the presence of light manufactured by a means selected from the group consisting of (1) thermal bonding a metal (2) pressure bonding a metal and (3) thermal/pressure bonding a metal onto ceramic particles, wherein: the metal is silver and the ceramic is titanium dioxide;the crystal form of the titanium dioxide is anatase, rutile or mixtures thereof; andthe sterilizing agent further includes adsorptive materials. 2. The sterilizing agent according to claim 1 wherein said metal is bonded ingrown into particles of the ceramic. 3. The sterilizing agent according to claim 1, wherein said adsorptive materials are Hydroxyapatite. 4. The sterilizing agent according to any one of claims 1, 2, and 3 wherein when the sterilizing agent is applied to Staphylococcus aureus, a decreasing Quantity of the Staphylococcus aureus after a predetermined time is larger than a decreasing quantity of the Staphylococcus aureus after the predetermined time when silver zinc zeolite is applied to the Staphylococcus aureus. 5. The method of making the sterilizing agent of (1) thermal bonding of claim 1 wherein said ceramic and said metal are bonded through a high temperature zone. 6. The method according to claim 5 wherein said high temperature zone is at about 2,900 degrees C. 7. The method of making the sterilizing agent of (2) pressure bonding of claim 1 wherein said ceramic and said metal are bonded through a ball mill. 8. The method according to claim 7 wherein said ball mill contains hard ball particles made from a material selected from the group consisting of alumina or zirconium and mixtures thereof. 9. The method of making the sterilizing agent using (3) thermal/pressure bonding of claim 1 wherein said ceramic and said metal are bonded with heat and pressure at the same time. 10. The method according to any one of claims 5, 7 and 9 wherein said ceramic and said metal particles are in a size range of 0.3 to 100 micrometers. 11. The method according to claim 10 wherein the particles of metal and ceramic are 0.3 to 50 micrometers. 12. The method according to claim 10 where the composition of the particles is 0.1% to 10% by weight silver and 90% to 99.9% by weight titanium dioxide. 13. A slurry sterilizing dispersing element comprising the sterilizing agent of any one of claims 1, 2 and 3 mixed with a liquid solution. 14. The slurry sterilizing dispersing element according to claim 13 wherein the liquid solution can be used safely on the human body and/or other surfaces. 15. A sterilizing means comprising the sterilizing agent of any one of claims 1, 2 and 3 provided in the fibres of a woven or non-woven fabric or paper, wood, plastics, metals, ceramics, compound products, paints, resin films, water, cleaning solutions, air filters and printing ink. 16. A method for sterilizing surfaces comprising the steps of applying the paint of any one of claims 1, 2 and 3 to housing materials for indoor use, furniture surface. 17. A method for giving fabric a sterilizing effect comprising the steps of impregnating any one of claims 1, 2 and 3 into the fibres of a woven or non-woven fabric. 18. A method for giving fabric a sterilizing effect comprising the steps of printing any one of claims 1, 2 and 3 to a surface of fibres of a woven or non-woven fabric. 19. A method for sterilizing surfaces comprising applying the resin film of any one of claims 1, 2 and 3 to housing materials for indoor use, furniture surface. 20. A sterilizing linen comprising the sterilizing agent of any one of claims 1, 2 and 3 provided in any one of cloth sheets, cloth pillow cases, towels, wash clothes and curtains. 21. Materials comprising the sterilizing agent of any one of claims 1, 2 and 3. 22. Products comprising the sterilizing agent of any one of claims 1, 2 and 3. 23. The materials of claim 21 provided in any one of adhesive bandage, ointment, gauze, catheter, and endoscope. 24. The materials of claim 21 provided in any one of drinking water, rain water, hot spring and cooling tower. 25. The materials of claim 21 provided in any one of hydroponics, aquaculture, soil amendment, washing and cleaning of vegetables, preservation for foodstuff, and antisepsis for foodstuff. 26. The materials of claim 21 provided in any one of wallpaper, ceiling material, and flooring. 27. The sterilizing agent according to claim 1 wherein the sterilizing agent is provided in any one of fibres of a woven or non-woven fabric or paper, wood, plastics, metals, ceramics, compound products, paints, resin films, water, cleaning solutions, air filters and printing ink. 28. A sterilizing agent according to claim 1, wherein the silver is bonded onto the titanium dioxide with thermal bonding, and when the sterilizing agent is applied to Staphylococcus aureus or Escherichia coli, a decreasing rate (%) of the Staphylococcus aureus or Escherichia coli after a predetermined time is larger than a decreasing rate (%) of the Staphylococcus aureus or Escherichia coli after the predetermined time when titanium dioxide and silver without thermal bonding or solely titanium dioxide is applied to the Staphylococcus aureus or Escherichia coli.
