Abstract

PURPOSE:To obtain high reliability by forming the film of crystallized glass contg. a specific ratio of oxides of >=1 kinds among LiO2, Na2O, MgO, BaO, TiO2, and ZrO2 by a sputtering method on butt surfaces and using lead glass for the glass material. CONSTITUTION:The crystallized glass contg. 0.5-15%, by weight, oxides of at least >=1 kinds among LiO2, NaO, MgO, BaO, TiO2, and ZrO2 is sputtered by using said glass as a sputtering target at the time of forming nonmagnetic films 13, 13' on the butt surfaces 11, 11'. Since the gap spacer is formed on the butt surface 11 of a magnetic core half body 10 in such a manner and since there is no generation of foam, the high-quality magnetic gap is efficiently formed. The good wettability with the lead glass 14 to be melted and packed into a winding groove 12 formed on the butt surfaces and the powerful adhesive power are thereby obtd. and, therefore the higher yield and reliability are obtd.
