A suction cup includes a suction cup main body, an attachment surface and a gel layer. The surface of the gel layer serves as a suction surface. In a method of manufacturing a suction cup, a cavity is formed in the inside of a common mold and a primary mold. Next, a synthetic resin material is injected into the cavity, to mold the suction cup main body. Subsequently, the primary mold is opened, to obtain the suction cup main body. Next, a secondary mold is mated to the common mold, whereby a cavity is formed in the inside of the common mold and the secondary mold. Subsequently, a gel is injected into the cavity, to mold the gel layer. Next, the secondary mold is opened, to obtain a suction cup composed of the gel layer and the suction cup main body, on the common mold.

What is claimed is: 1. A method of manufacturing a suction cup, the suction cup having a suction cup main body formed from an elastic synthetic resin material, an attachment surface formed on said suction cup main body, and a gel layer provided integrally with said attachment surface and formed of a gel, the surface of said gel layer serving as a suction surface, the method comprising: mating a primary mold with a common mold to form a suction main body molding cavity in the inside of said molds so that said attachment surface molded in a shape corresponding to said suction cup main body fronts on said primary mold; injecting said synthetic resin material in a fluid state into said suction cup main body molding cavity to mold said suction cup main body, opening said primary mold to obtain said suction cup main body on said common mold, with said attachment surface directed in the direction of separating said primary mold; then mating a secondary mold with said common mold to form a gel layer molding cavity having a shape corresponding to said gel layer in the inside of said molds and between said mold and said attachment surface; and injecting said gel in a fluid state into said gel layer molding cavity to mold said gel layer on said attachment surface, and opening said secondary mold to obtain said suction cup. 2. The method of manufacturing a suction cup as set forth in claim 1, wherein said synthetic resin material is thermoplastic, and the injection molding of said suction cup main body is conducted by injecting said synthetic resin material in a molten state into said suction cup main body molding cavity, followed by cooling. 3. The method of manufacturing a suction cup as set forth in claim 1, wherein said synthetic resin material is thermosetting, and the injection molding of said suction cup main body is conducted by injecting said synthetic resin material in a fluid state into said suction cup main body molding cavity, followed by heating and then cooling. 4. The method of manufacturing a suction cup as set forth in claim 1, wherein said gel is thermoplastic, and the injection molding of said gel layer is conducted by injecting said gel in a molten state into said gel layer molding cavity, followed by cooling. 5. The method of manufacturing a suction cup as set forth in claim 1, wherein said gel is thermosetting, and the injection molding of said gel layer is conducted by injecting said gel in a fluid state into said gel layer molding cavity, followed by heating and then cooling. 6. The method of manufacturing a suction cup as set forth in claim 1, wherein said gel is weatherproof. 7. The method of manufacturing a suction cup as set forth in claim 1, wherein said attachment surface is formed in a concave shape. 8. The method of manufacturing a suction cup as set forth in claim 1, wherein said suction surface is formed in a concave shape. 9. The method of manufacturing a suction cup as set forth in claim 1, wherein said gel layer is composed of a jelly-like material.
