Abstract

According to one embodiment, a semiconductor module comprises a substrate, a first wiring, an electrode pad, a junction, an oscillator, and a detector. The first wiring is disposed on the substrate, and has a characteristic impedance Z0. The electrode pad is connected to the first wiring. The junction is disposed on the electrode pad, and has an impedance Z1. The oscillator is disposed in contact with the first wiring, and oscillates a pulse wave of a voltage toward the junction via the first wiring. The detector is disposed in contact with the first wiring, and detects an output wave of the pulse wave from the junction. The characteristic impedance Z0 and the impedance Z1 satisfy a following relationship (1),
