1. A membrane material for a gas holder, which is used in a gas holder for storing or recovering gas, comprising at least 4 layers of a protective layer, a base fabric layer, a gas barrier layer and a protective layer laminated in this order, wherein at least one protective layer constituting the membrane material comprises a polyolefin resin,wherein a film-like polyurethane resin layer is laminated on one surface or both surfaces of the base fabric layer. 2. The membrane material for a gas holder according to claim 1, wherein the base fabric is a woven fabric, and the product of the fineness (dtex) of yarns and the density (ends/inch) thereof is from 2,500 to 5,000. 3. The membrane material for a gas holder according to claim 1, wherein the polyurethane resin layer has a thickness of 5 to 50 μm. 4. A gas holder comprising the membrane material for a gas holder according to claim 1. 5. The membrane material for a gas holder according to claim 2, wherein the polyurethane resin layer has a thickness of 5 to 50 μm. 6. A gas holder comprising the membrane material for a gas holder according to claim 2. 7. A gas holder comprising the membrane material for a gas holder according to claim 3. 8. A gas holder comprising the membrane material for a gas holder according to claim 5. 9. The membrane material for a gas holder according to claim 1, wherein the gas barrier layer is at least laminated on the film-like polyurethane resin layer-laminated side of the base fabric layer. 10. The membrane material for a gas holder according to claim 1, wherein a resin used for the protective layer is at least one selected from the group consisting of a polyethylene resin, a polyurethane resin (excepting the film-like polyurethane resin previously laminated on the base fabric layer), a vinyl chloride resin, an acrylic resin and a polyester resin. 11. The membrane material for a gas holder according to claim 2, wherein a material used for the woven fabric is at least one selected from the group consisting of a polyester, a nylon, a carbon fiber, an aramid fiber and a glass fiber. 12. The membrane material for a gas holder according to claim 1, wherein a film used for the gas barrier layer is at least one selected from the group consisting of a polyethylene naphthalate film, a polyamide film, a polyvinylidene chloride film and an ethylene-vinyl alcohol copolymer film. 13. The membrane material for a gas holder according to claim 1, wherein a basis weight of the base fabric layer is from 20 to 100 g/m2. 14. The membrane material for a gas holder according to claim 1, wherein a thickness of the gas barrier layer is from 3 to 30 μm. 15. The membrane material for a gas holder according to claim 1, wherein a thickness of the protective layer used on the base fabric layer side or the gas barrier layer side is from 5 to 180 μm. 16. The membrane material for a gas holder according to claim 1, wherein a total thickness of the membrane material is from 150 to 300 μm.
