An electronic controller having a circuit board with an element disposed thereon, a base member with the circuit board adhered thereon and a lead terminal in an electrical connection with the circuit board includes as the elements thick film resistors and electric components soldered by solder on a bottom side of the circuit board, and also includes electronic components including bare chips being at least wired without soldering on a top surface of the circuit board. The electronic controller has a first concave portion at a position corresponding to a position of the components on a surface that has the circuit board of the base member adhered thereon, and the circuit board is molded by a sealing resin so as to expose a portion of the base member and a portion of the lead terminal.
