Abstract
A highly reliable magnetic head which exhibits excellent magnetic characteristics and is free from film defects can be produced by using a silicone-containing polyimide resin as a material for insulation layers to thereby form homogeneous and flat insulation layers. Such a polyimide resin is suitable for other multi-layered stereo-wiring structures.
