A gas cartridge is provided to disperse depression deformation of an inner bag to a plurality of parts by preventing concentration of stress only on a part of the inner bag by compression gas, thereby preventing generation of a crack or a pin hole in the inner bag. A gas cartridge includes a metal outer can(1), a metal inner bag(2), and a deformation inducing part(P1). The inner bag is arranged inside the outer can and has a predetermined thickness. The inner bag is filled with fuel gas(G1). A space between the outer can and the inner bag is filled with compression gas(G2) to crash the inner bag according to the gas consumption. The deformation inducing part is formed as one body with the inner bag and induces deformation of the inner bag when applied with pressing force of the compression gas according to the compression gas consumption. The deformation inducing part has a plurality of long recessed parts lengthwise.
