Electronic module

An electronic module for a vehicle, comprising:

• a casing that has a through hole that is in communication with the inside and the outside of the casing;
• and
• a bus bar that includes a strip-shaped connection terminal to be fitted into a connector of a fuse, the connection terminal including one end portion in its longitudinal direction that is exposed to the outside of the casing as a result of being passed through the through hole,
• wherein the casing has a first flat surface in a peripheral edge portion of the insertion hole, on the inner side of the casing,
• the connection terminal includes an extension portion that is located on another end side in the longitudinal direction with respect to the one end portion and extends in a width direction of the connection terminal, and
• the extension portion has a second flat surface that comes into contact with the first flat surface from the inner side of the casing, wherein the extension portion is provided on each side of the connection terminal in the width direction,
• a support portion that includes two recesses in which the two extension portions are fitted is provided in the peripheral edge portion so as to protrude toward the inner side of the casing, and
• the two recesses each have the first flat surface and inner surfaces that come into contact with opposite surfaces of a corresponding one of the extension portions, and
• wherein each extension portion has a rectangular shape,
• each extension portion spans from an intermediate portion of the connection terminal in its longitudinal direction to another end of the connection terminal in its longitudinal direction, and
• a corner portion of each extension portion that is adjacent to the second flat surface in an extension direction is chamfered.
