Abstract: There is provided magnetic field generating member including: permanent magnet portion that has first magnetic pole portion of which one surface side becomes a first magnetic pole surface and second magnetic pole portion which is adjacent to first magnetic pole portion and of which one surface side becomes a second magnetic pole surface. In addition, the magnetic field generating member includes first magnetic body disposed on one surface side in at least one of first magnetic pole portion and second magnetic pole portion and second magnetic body disposed on the other surface side of permanent magnet portion so as to straddle boundary between first magnetic pole portion and second magnetic pole portion.

Abstract: A semiconductor device includes an input circuit, an output circuit, an insulation circuit, and a semiconductor substrate. The insulation circuit includes at least one capacitor for electrically insulating the input circuit and the output circuit from each other. The at least one capacitor has two electrodes, one of which being electrically connected to the input circuit, and the other of which being electrically connected to the output circuit. The semiconductor device further includes an insulation film that is made of dielectric material and is provided between the at least one capacitor and the semiconductor substrate in a thickness direction of the semiconductor substrate.
