Claims

[Scope of utility model registration request]

A flexible, transparent gas-impermeable sheet is polymerized on the surface of a gas-permeable sheet impregnated with a detection substance that changes color when it reacts with the pinhole detection gas, and the edges of both sheets are adhered to each other. A pinhole detection sheet with double-sided adhesive tape attached to the edge of the back side of a gas permeable sheet.
