Electronic control unit case

An electronic control unit case (13) is disclosed, wherein a coil (12) is provided on the top surface of a block housing control equipment (11) for operating the same. The case (13) protrudes a sidewall (10) from the circumferential part of a plate portion (15) thereof in which a bus bar (14) is embeded and is secured onto the block (11) with the sidewall (16) resting at its end surface on the block while covering the coil (12). An electronic control unit (19) is attached to the back surface of the plate portion (15), a through hole (20) is formed in the plate portion (15) in correspondence to the coil (12), and a terminal (21) of the coil (12) and a terminal portion (22) of the bus bar (14) are joined to each other in the through hole (20). In a plane which is parallel to the axis of the coil (12) as well as to a plane in which a portion embeded in the plate portion (15) of the bus bar (14) extends, the terminal portion (22) of the bus bar (14) is bent twice or the terminal portion (22) of the bus bar (14) and the coil terminal (21) are bent both once so that a point where the terminal portion (22) of the bus bar (14) and the coil terminal (21) are joined to each other is offset (A) from the portion embeded in the plate portion (15) of the bus bar (14) in a direction parallel to the coil axis or is further offset from a root portion of the coil terminal (21) in the same direction as the portion embeded in the plate portion (15) of the bus bar (14) extends. Further, the through hole (20) is formed to extend with a thin width in the same direction as said portion embeded in said plate portion (15) of said bus bar (14) extends.
