PROBLEM TO BE SOLVED: To improve output characteristics and the freedom of head designing. SOLUTION: This magnetic head 1 is constructed in such a manner that a pair of magnetic core halves 2, 3 are butted together to form a magnetic path, and a nonmagnetic film 6 is formed in a butted surface to form a magnetic gap G. In this case, a coil is wound on at least one of the pair of magnetic core halves 2, 3, grooves 10a, 10b are formed on a surface other than the butted surface of the coil wound part to reduce the volume of the magnetic core part in which the magnetic path is formed, and dimensions A of the grooves 10a, 10b in a depth direction are set to 20 to 50% of the dimensions B of the magnetic core halves 2, 3 in the same direction.
