A semiconductor device (10) of the present invention includes at least one circuit unit (41, 42, 43) which includes: a device main body (20); and a power supply terminal (31, 32, 33), an output terminal (34, 35, 36), and a ground terminal (37, 38, 39) which protrude from the device main body (20). The output terminal (34, 35, 36) protrudes from the device main body (20) in an opposite direction to the ground terminal (37, 38, 39). The power supply terminal (31, 32, 33) protrudes in a same direction as the ground terminal (37, 38, 39) and is positioned so as to be shifted in a direction orthogonal to an arrangement direction of the output terminal (34, 35, 36) and the ground terminal (37, 38, 39).
