A semiconductor module includes: a semiconductor element; first and second main current passages for energizing the semiconductor element, the first and second main current passages being opposed to each other in such a manner that a first energization direction of the first main current passage is opposite to a second energization direction of the second main current passage, or an angle between the first energization direction and the second energization direction is an obtuse angle; and a coil unit sandwiched between the first and second main current passages. The coil unit includes a coil, which generates an induced electromotive force when a magnetic flux interlinks with the coil, the magnetic flux being generated when current flows through the first and second main current passages.
