Abstract

PURPOSE: To prevent deterioration of characteristic and enhance the precision, by providing a specific groove in a core block having a gap, and cutting the common part after affixing a nonmagnetic material into this groove part with an adhesive.
CONSTITUTION: Core blocks 11, 11 such as oxide ferromagnetic material are jointed together by means of a nonmagnetic material such as glass, and a gap 12 is formed. For shielding purpose, a comb-tooth groove part 13 is provided in the block 11, and tooth parts 11a, 11a having large thickness and small thickness are formed alternately. A laminar nonmagnetic material 14 such as glass is inserted into this groove part 13, and is affixed by means of a glass bar 15 which is melted to be used as an adhesive, thus forming a shield part. Next, the block 11 is cut off in the short dashes line part, separating the tooth parts 11a, 11b magnetically, and a front core block 16 having a gap 17 is obtained. The end of the leg part furnished with the coil 19 of back core block 18 is adhered to the tooth part 11a, then the short dashes line part of the block 18 is cut off.
