(57) Abstract :
To obtain an electronic control apparatus enabling a reduction in size as well as increases in output and in lifetime, the electronic
control apparatus includes: a housing (3) made of an insulating resin, having opening portions on both ends; a heat sink (5) attached to
one of the ends of the housing (3), the heat sink (5) having a surface on a housing (3) side, on which a semiconductor switching
element (2) is mounted; and a circuit board (4) provided to be opposed to the heat sink (5), in which a plurality of low-current
components including a microcomputer (41) for controlling driving of the semiconductor switching element (2) are mounted on one
surface of the circuit board (4), whereas a plurality of high-current components including a capacitor for absorbing a ripple of a
current flowing through the semiconductor switching element (2) are mounted on another surface of the circuit board (4).
