Claim 0:
1. A gas generator, comprising:
a housing having a first container including a first bottom surface portion and a second container including a second bottom surface portion, the housing being formed by joining the first container and the second container at respective predetermined lateral side portions;
an igniter attached to a mounting hole, the mounting hole connecting an inside and an outside of the housing and being formed in the second bottom surface portion of the second container;
a gas generating agent that is combusted by an operation of the igniter being filled in a predetermined region in the housing;
a gas discharge port through which a combustion gas generated by combustion of the gas generating agent is released to the outside of the housing being formed in at least one of the first container and the second container; and
the igniter being fixed to the second bottom surface portion of the second container by a predetermined resin material in a state where the igniter is penetrating the mounting hole, wherein
the mounting hole has:
a passing region through which the igniter is passing in the mounting hole in a state where the igniter is fixed; and
a tip region around the passing region, the tip region being located in a radial direction of the housing outside an outer periphery of the igniter when the igniter is projected onto the second bottom surface portion in a state where the igniter is fixed, in which paired edge portions defining a width of the tip region intersect with each other to form a tip portion having a convex shape protruding outward in the radial direction of the housing on an outermost side of the tip region.
