<P>PROBLEM TO BE SOLVED: To provide an electronic control apparatus which reduces the cost while reducing the size of the entire apparatus. <P>SOLUTION: Power distribution patterns of a power electronic circuit and a filter electronic circuit are integrally formed with a bus bar assembly 13 molded by a resin material. Further, a second shunt resistor 18, detecting a driving current of an electric motor, is provided at the bus bar assembly, and a side piece 22b of a heat transfer member 22 is joined to a side part 18b of the second shunt resistor. Furthermore, an upper surface of an upper end part 9a of a protruding part 9, which is integrally provided with a housing body 3 made of an aluminium alloy material and serving as a heat sink, is in contact with a bottom side part 22a of the heat transfer member through a heat radiation sheet 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
