Abstract

A current sensor device includes a bus bar that is to be connected to a plate-shaped terminal of a semiconductor device, a magnetoelectric conversion element that is configured to detect a current flowing through the bus bar, and a resin portion that integrally holds the magnetoelectric conversion element and the bus bar. The bus bar has one end protruding from the resin portion, and the one end of the bus bar includes a penetration portion defined by wall surfaces. The wall surfaces includes a pair of opposing wall surfaces opposing to each other. At least one of the opposing wall surfaces is configured to be connected to the terminal.
