Abstract

PURPOSE:To firmly hold a gap, by forming nonmagnetic reinforcing parts on both side planes of the head part of a pair of magnetic cores including a gap part in a track width direction, respectively, and applying spot welding confronting nonmagnetic reinforcing parts. CONSTITUTION:After each block half body is superposed, and the joint part of the nonmagnetic reinforcing parts 12a-12d is welded with spots 15a and 15b of around 100mumphi by using a laser, etc., thereby, the gaps G1 and G2 are held. Also, the nonmagnetic reinforcing parts 12a-12d are provided sufficient absorption characteristics for a laser beam. Furthermore, the holding of the gap is performed by applying the vacuum impregnation of bonding resin from a rearward. In such a way, the gap is held firmly, and it is possible to prevent the deviation of the gap in a cutting process in a manufacturing process or under a condition of high temperature and high humidity from being generated, and to improve reliability.
