<;P>;PROBLEM TO BE SOLVED: To provide a plastic greenhouse enabling achievement of a film double layer structure with an easy structure at a low cost. <;P>;SOLUTION: This plastic greenhouse is formed by covering the periphery of a framework constructed with a plurality of frame members with a resin film. In more details, the greenhouse is formed by tightly stretching an outer resin film with a prescribed film stopping means on the outer surface of the frame members forming at least a gable surface, forming a slot part extending to the longitudinal direction on the inner surface of the frame members, tightly stretching an inner resin film on the slot part through attaching a film press plate holding by pressure the resin film between the slot part, and setting a gable surface of a film double layer structure, tightly stretched with resin films each on the front and back of the frame member. <;P>;COPYRIGHT: (C)2008,JPO&INPIT
