PURPOSE:To easily and accurately attain an inter-gap length and a head height difference of a double-azimuth magnetic head by joining positive and negative azimuth core blocks with a nonmagnetic body between them. CONSTITUTION:A second core block half body 14 and a first core block half body 10 are fitted to each other with a track abutting groove 9 between them so that a magnetic body slope 9a of the groove 9 and a gap holding film 13 formed on the second core block half body 14 face each other and are brought into contact with each other, and a nonmagnetic joint member 15 is inserted to a glass filling groove 12 and a winding groove 11 and is fused and joined. A nonmagnetic body 2 whose both faces a low-melting point glass 20 is stuck is held between a positive azimuth core block 17 and a negative azimuth core block 19, and this glass is fused to join both core blocks 17 and 19. At this time, an inter-gap length l and a head height difference DELTAH are adjusted to regular values. Thus, the double-azimuth magnetic head where dimensions and the quantity of the inter-gap length and the head height difference are stable is obtained with a good yield.
