An improved magnetic head is produced by utilizing as a spacer for regulating the width of the head gap thereof a non-magnetic oxide film formed by applying a vapor of at least one volatile metal alkoxide capable of forming a non-magnetic metal oxide by thermal decomposition reaction, e.g. an alkoxide of such a metal as A1, Ti, Zr, Si or Hf, onto the surface of a ferrite core heated to above the thermal decomposition temperature of said alkoxide, thereby bringing about on the core surface the thermal decomposition reaction of said alkoxide.
