Abstract

PURPOSE: To simplify the bonding process, stabilize the bonding, and equalize the characteristics in each channel, by integrally bonding the front core block to the back core fitted in the groove part of back core support block.
CONSTITUTION: Core blocks 12, 12 are bonded with nonmagnetic material, and a front core block 11 having a gap 13 is formed. A U-shaped back core 16 wound with a coil 15 is fitted into a groove 14a in a back core support block 14 which corresponds to said block 11, and the block 11 is placed on and bonded to the end of the core 16. Next, a filler 17 such as resin is charged in the gap between cores 16 and is solidified. Then, a notch reaching the filler 17 is provided in the block 11, which is divided into multiple front cores 11a corresponding to the cores 16. At this time, the width W1 of core 11a is made wider than the width W2 of core 16. Into each notch in the block 11 is inserted and secured a shield member 18 in sandwich form of ferromagnetic material held by nonmagnetic material.
