PROBLEM TO BE SOLVED: To provide a small magnetic field detection device.SOLUTION: The magnetic field detection device comprises: a substrate; a magnetic field detector having the normal of the principal surface of the substrate as a normal and arranged on a first plane above the principal surface of the substrate; a permanent magnet having the normal of the principal surface of the substrate different from the first plane as a normal and arranged in the magnetization direction on a second plane separated from the substrate above the principal surface of the substrate; an electrode terminal arranged on a third plane different from the first and second planes, separated from the first and second flat planes and the principal surface of the substrate, having the normal of the principal surface of the substrate as a normal, separated from the substrate above the principal surface of the substrate and connected with the magnetic field detector; and an internal wiring connected with the electrode terminal and the magnetic field detector. The magnetic field detector, the permanent magnet, the electrode terminal and the internal wiring are integrally formed above the principal surface of the substrate. 【課題】小型な磁界検出装置を提供することを目的とする。【解決手段】基板と、基板の主面の法線を法線とする基板の主面上の第１の平面に配置された磁界検出部と、第１の平面とは異なる基板の主面を法線を法線とする基板の主面上の基板と離間した第２の平面に配置された着磁方向を有する永久磁石と、第１および第２の平面とは異なり、第１および第２の平面より基板の主面から離れた基板の主面の法線を法線とする基板の主面上の基板と離間した第３の平面に配置されるとともに、磁界検出部と接続された電極端子と、電極端子および磁界検出部と接続される内部配線とを有し、基板の主面上に磁界検出部と永久磁石と電極端子と内部配線とが一体となって形成されている磁界検出装置である。【選択図】図２
