Abstract
A magnetism detection device includes: a substrate having a substrate front surface; a magnetism detection element provided at the substrate front surface; a first terminal and a second terminal arranged at positions on the substrate front surface separated from the magnetism detection element; and a front surface wiring formed over the substrate front surface and configured to electrically connect the first terminal and the second terminal, wherein the front surface wiring includes: a first wiring applying a magnetic field including a first direction component along a thickness direction of the substrate to the magnetism detection element when a current flows from the first terminal to the second terminal; and a second wiring applying a magnetic field including a second direction component, which is in an opposite direction of the first direction component, to the magnetism detection element when the current flows from the first terminal to the second terminal.
