Abstract
A power semiconductor apparatus includes a power semiconductor element having low and high potential side electrodes and a sense electrode, high and low potential side conductors electrically connected with the high potential side electrodes, respectively, a sense wiring electrically connected with the sense electrode, and a first metal portion facing the low potential side conductor or the low potential side conductor across the sense wiring. When viewed from an array direction of the sense wiring and the first metal portion, the sense wiring has a facing portion facing the high or low potential side conductor, the first metal portion forms a recess in a part overlapping the facing portion, and a depth of the recess is formed such that a distance between a bottom of the recess and the sense wiring is larger than a distance between the sense wiring and the high or low potential side conductor.
