Abstract

A head base has at least one head chip fixed thereto. A position of the head chip is adjusted to a predetermined position by applying a laser beam to the head base to cause plastic deformation of the head base. Appropriate laser radiation conditions are set depending upon a necessary amount of positional adjustment of the head chip fixed to the head base.
