PROBLEM TO BE SOLVED: To provide a gas-sealed bag which is easy in transportation and manufacture, and in which a configuration for protecting the edge portion of a package is formed and which has a protective function which can be accommodated to the protection of an edge section when expanding the gas-sealed bag by applying a gas. SOLUTION: The gas-sealed bag made by superimposing a plastic film, sealing a peripheral rim section with heat deposition or the like and enclosing the gas inside has a triangular prism configuration which makes the bottom an isosceles triangle Q and is the gas-sealed bag 10' of which the face meeting its apex angle is empty.
