PURPOSE:To reduce crosstalk, to simplify production processes and to attain massproduction by forming a magnetic circuit including plural tracks consisting of ferromagnetic films on the butt surface of substrates to make both substrates butt against each other. CONSTITUTION:The ferromagnetic film 15 is formed on the whole surface of the butt surfaces 16, 17 including the winding groove 14 of non-magnetic substrates 12, 13 and plural tracks 18a, 18b are formed by etching processing or the like. A separation band 19 is formed between the tracks. A core semi-body on which a non-magnetic thin film 20 is formed for forming a magnetic gas is joined with the butt surfaces on the leading end parts of the tracks 18a, 18b to obtain a block A. The block A is cut off along the X-X line and the 2nd winding groove 21 is formed to obtain a core B. A ferromagnetic thin chip 23 is formed on the cut surface 22, a winding 24 is wound around the tracks 18a, 18b through the winding grooves 14, 21 and the magnetic thin film 23 formation surface is joined with the ferromagnetic thin film 26 formation surface, so that a magnetic head 27 of reduced crosstalk is obtained.
