Patent ID: 7679914

Claim:
An electronic controller comprising: a circuit board that has an element mounted thereon for composing a circuit; a base member that has the circuit board adhesively fixed thereon; and an external terminal that is electrically connected to the circuit board, wherein a base member facing side of the circuit board that is adhered to the base member has as the element a thick film resistor disposed thereon and an electronic component that is mounted thereon by soldering, a reverse side of the circuit board that opposes the base member facing side to be adhered to the circuit board has as the element an electronic component that includes a bare-chip that is at least connected by wire for mounting without soldering, a first side of the base member that has the circuit board adhered thereto has a first concave portion at a position that corresponds to the electronic component being mounted on the circuit board, the circuit board is molded with a part of the base member and a part of the external terminal respectively being exposed from molding, and the first concave portion has in a planar direction of the circuit board at least one of an end that has an opening on an end surface of the base member and a portion that extends out of a disposition area of the circuit board on the base member.
