PROBLEM TO BE SOLVED: To provide a control device of a vehicular fuel pump capable of minimizing enlargement even if a noise filter circuit is arranged. SOLUTION: A heat sink 13 is divided into a heat sink body 15 and a sub-heat sink 16, and components 3, 5, 7, 9 and 11 of a control circuit including the noise filter circuit, are respectively mounted on the heat sink body 15 and the sub-heat sink 16, and the heat sink body 15 and the sub-heat sink 16 are joined. Thus, since the components of the control circuit vertically overlap with each other, the footprint of the control device 1 can be reduced. COPYRIGHT: (C)2009,JPO&INPIT
