Claims

[Scope of utility model registration request]

A head part storage recess is formed on the mounting surface side of the ceramic case, a head part consisting of a head core and a coil wound therein is provided in the recess, and is fixed with mold resin. A magnetic erasing head in which a head core is exposed to form a tape sliding surface, wherein a convex portion serving as a mounting reference surface higher than the periphery of the head storage recess is formed on the mounting surface of the case, and the ceramic case A magnetic erasing head characterized in that only one through hole for attachment is formed so as to penetrate through a side surface.
