1. A fixing structure of an electrode terminal, comprising:
a battery housing having an open end at a first side and a bottom with a perforation hole at a second side opposite the first side, the bottom having a first surface and a second surface opposite the first surface;
an electrode terminal fixed to the bottom; and
a terminal gasket located between the electrode terminal and the bottom,
wherein the electrode terminal includes:
a neck portion having a cross section smaller than a cross section of the perforation hole, the neck portion being inserted into the perforation hole;
a head portion connected to a first end of the neck portion, the head portion having a cross section larger than the cross section of the perforation hole, the head portion extending along the first surface of the bottom;
a protrusion connected to a second end of the neck portion opposite the first end along an axial direction of the battery housing from the second surface of the bottom;
a diameter-enlarged portion extending in a radial direction from the protrusion; and
a front end surface at an axial end of the protrusion, and
wherein the diameter-enlarged portion is a fastening member physically coupled to an outer circumference of the protrusion.
