A semiconductor device suppresses a magnetic field caused by a current loop formed by a signal wiring and a return path wiring, to reduce transmission loss of a high-speed signal. The semiconductor device includes a signal current path connected from a signal pad to a first external terminal via a first bonding wire and an interposer, and a current return path connected from a second external terminal provided adjacent to the first external terminal to a second pad provided adjacent to the signal pad via the interposer essentially on the same plane. The signal current path and the current return path are positioned so that they intersect with each other, thereby reversing the direction of a loop through which the current flows, and as a result, magnetic fields caused by the current loop formed by the signal current path and the current return path cancel each other.
