An electronic unit includes a casing, printed circuit board, connector-receiving part, connecting member, and fixing member. The connector-receiving part is formed integrally with a first casing member of the casing. The connecting member includes a terminal and a body of the connecting member attached to the casing. The terminal includes first and second connecting parts. The center of the terminal is attached to the body of the connecting member. A connector of an opposite side is inserted into the connector-receiving part along the longitudinal direction of the first connecting part. The first casing member and the connecting member are provided with respective holes, which communicate to each other. The fixing member includes a boss part. The boss part is press-fitted in the holes along the longitudinal direction of the second connecting part so as to fix the connecting member to the first casing member.
