ABSTRACT:
A magnetic head in which a pair of magnetic core halves each having a winding slot for placing a coil are abutted and unified to each other by thin magnetic metal films interposed in-between, and in which a magnetic gap is formed between abutting surfaces of the magnetic core halves. A bend is formed in the winding slot for bending the thin magnetic metal film at an acute angle when seen in cross-section. The magnetic head has a structure for prohibiting peeling of the thin magnetic metal film.
