摘要： PURPOSE:To eliminate the evil influence of the back gap in a closed magnetic path upon the closed magnetic path by providing the 3rd block which is adhered fixedly without the intervention of an adhesive in the back gap. CONSTITUTION:Flat abutting parts 30 and 27 of core blocks 21 and 22 are joined tightly to form the back gap which is narrow enough to ignore magnetically. Therefore, the core blocks 21 and 22 form the closed magnetic path l connecting the circumference of a cut 26, the back gap, and an upper corner part 28 from an upper corner part 25. Further, the core blocks 21 and 22 are fixed to the 3rd block 23 as a fitting substrate through adhered parts 34 and 35 in a tight joined state by an Ag brazing material 33. Consequently, no brazing material is interposed in the back gap, so the evil influence of the back gap upon the closed magnetic path is eliminated.
