The present invention provides a circuit device which insures highly-reliable electrical connections even when used in environments involving large temperature variations, and which can be easily assembled. Board assembly (10) has a housing (50) which is mounted on an edge (150) of a circuit board (100). Edge (150) includes protruding sections (160) on which a plurality of contact pads (180) are aligned. The housing (50) accommodates the protruding sections (160) inside slots (52), which are formed inside the housing (50). Reinforcing sections (55) are disposed on both sides along the lengths of the slots (52). A connector, which engages with a mating connector, is formed by the protruding sections (160) and the housing (50). Since the edge (150) of the circuit board (100) is maintained in a substantially flat-plate shape even in cases where deformation caused by heat occurs in other portions of the circuit board (100), highly reliable electrical connections with mating connectors can be realized.
