A magnetic path is formed by means of: a center core (1) disposed inside a first coil (2) and a second coil (3); a first side core (4) and a second side core (6) which are disposed outside the first coil (2) and the second coil (3) and which are in contact with the center core (1); and a magnet (5) disposed between the first side core (4) and the second side core (6). The shape of a space formed at the portion of contact between the first side core (4) and the second side core (6) is a shape which forms an insertion portion for inserting the magnet (5), which is disposed obliquely relative to the magnetic path, and voids perpendicular to the magnetic path at both ends of the magnet (5). |
