Abstract
PURPOSE: To simplify the manufacturing process and to increase the yield by manufacturing the core block incorporating the magnetic circuit and the gap forming part, forming the goove leaving the both ends of the gap forming part and melting glass in the groove.
CONSTITUTION: The block 12 where the magnetic circuit 10 and the gap forming part 11 are incorporated is formed. In this case, the notch 14 is formed with machine processing by leaving the size 15 (e.g., about 30μm) slightly greater than the depth of gap. Further, the groove 16 is formed with machine or laser processing by leaving the width 17 at both ends, and after giving molten glass 18 to the groove 16, the gap forming part 11 is polished to specify the depth of gap 19. Finally, this block is sliced orthogonally with the groove 16 to obtain the magnetic core. Thus, the manufacturing process is simplified, the accuracy of size is increased and the yield can be increased.
