Claim 0:
1. A power semiconductor module, comprising:
a first external terminal, a second external terminal, and a third external terminal;
a half-bridge circuit including a first power semiconductor element and a second power semiconductor element that are connected in series with each other between the first external terminal and the second external terminal;
a first wiring member that connects a high-potential-side main electrode of the first power semiconductor element to the first external terminal;
a second wiring member that connects a low-potential-side main electrode of the second power semiconductor element to the second external terminal;
a third wiring member that connects an output of the half-bridge circuit to the third external terminal; and
a first corrosion sensor disposed in a vicinity of the first wiring member for detecting corrosion of the first wiring member, a second corrosion sensor disposed in a vicinity of the second wiring member for detecting corrosion of the second wiring member, and a third corrosion sensor disposed in a vicinity of the third wiring member for detecting corrosion of the third wiring member.
