Since the jig 3 has a thin side mating surface 3a so as not to contact the head base, it is necessary to make the side mating surface 3a thin so as not to contact the head base.As shown in FIG. Since a gap a is required between the two, it is necessary to increase accuracy in the vertical direction, and a microscope is required for this operation, resulting in poor workability.

The width of one side is cut off by the width w with respect to the center position to make it asymmetrical, so that when the magnetic head chip 4 is installed in the normal position, the end part will be aligned with the mounting surface 5.
It is formed so as to slightly protrude from the side edge of a by a width b.

省略することができるものである。 Therefore, when adhering the magnetic head chip to the magnetic head base of the present invention, as shown in FIG. 5, an L-shaped jig 6 is applied to align the mounting position of the magnetic head chip 3. At this time, as shown in FIG. 6, a gap of width b is created between the head base 4 and the head base 4.
Since it does not get in the way of the jig 6 and there is no need to adjust the position in the vertical direction, work using a microscope can also be omitted.
