PURPOSE:To provide a printed circuit board unit including a heat sink in a housing and a connector for an external device, in which the clearance between the housing and the connector is decreased. CONSTITUTION:A printed circuit board 62 is placed in a lower housing 61, which supports a heat sink 63 on which is fixed a component 62A that is mounted on the printed circuit board. The heat sink includes a fixture 63c to which a connector 62b and the printed circuit board 62 are fixed, and a fixture 63d to which an upper housing 8 is connected. The upper housing, covering the upper opening of the lower housing, includes a connector mount 8A for receiving the connector 62b. In this structure, there is no need for considering the printed circuit board and circuit components to set the clearance between the connector and connector mount. |
