Abstract: An electronic circuit device 21 consists of a connector 23 provided with guide projections 45, a circuit board 24 on which the connector 23 is mounted, and a case 22 provided with guide recesses 36. Since the guide recesses 36 are broader in width at the end portions of the side walls of the case 22, and the guide projections 45 are narrower in width at the side where the connector 23 is first inserted, no high positional accuracy is required when the connector is received in the case. Both the guide recesses 36 and the guide projections 45 include inclined faces 37, 37, 47, 47 to form a V-shape.
