PURPOSE:To assemble a magnetic head with high accuracy by providing a non-crystallized glass layer in advance at the facing planes of magnetic cores which form a gap, and using a crystallized glass as a high melting point glass which bonds the magnetic cores with each other. CONSTITUTION:A magnetic core 10 having a U type of cross section, and a magnetic core 12 having an I type of cross section are joined after providing in advance a gap layer 14 of non-crystallized glass with a sputtering method. High melting point glass bars 18 easy to be crystallized are placed respectively at a winding window 16 and a notched part at a back gap, and a coupled body is inserted and heated in a furnace, and a gap part is stuck by raising a temperature up to the working temperature of the glass bar 18, and softening and melting the bar. At such a time, a spacer 20 to regulate a gap length L is inserted in advance. Next, a non-magnetic member 24 is attached at the side plane of the magnetic core 12 having the I type of cross section, and a low melting point glass bar 26 is placed at the upper notch of the member, then the member is stuck by raising the temperature up to the working temperature of the glass, and melting and pouring down the glass.
