Abstract
A magnetic head reduces a slant of a magnetic head chip in comparison with a conventional case. The magnetic head is produced by a manufacturing method. A ridge on a back surface side of a magnetic chip is brought into contact with a chip attachment surface of a chip attachment base. A height of the magnetic head chip is adjusted by using the ridge as a fulcrum.
