A magnetic head is disclosed. The magnetic head has a block which is formed of a first magnetic material in which a groove for a winding is formed, a first magnetic film which is deposited on a surface of the block in which the groove is formed and is formed of a second magnetic material having a higher saturation magnetic flux density than that of the first magnetic material, a nonmagnetic film which is formed on the first magnetic film and serves as a magnetic gap, a second magnetic film which is deposited on the nonmagnetic film and is formed of the second magnetic material, and a reinforcing block. A portion of the reinforcing block on the side of a magnetic recording medium slide surface is formed of a nonmagnetic material, and the other portion is formed of a magnetic material. A magnetic material-side boundary portion between the nonmagnetic and magnetic materials is inclined to form an acute angle with the nonmagnetic film.
