ABSTRACT:
A magnetic head suspension having a thin metallic plate as a substrate which is caused to have a new function besides a function as a spring. The magnetic head suspension plural lines for connecting a magnetic head and a control circuit board to each other are formed over a thin metallic plate having a spring property through an insulating layer, and are integrated with the thin metallic plate A metallic pad made of a same metal layer as the plural lines is formed independently of the lines, an opening is made in a portion of the metallic pad to penetrate the insulating layer and then to reach the thin metallic plate, and an electroconductive region is formed into the opening by metal plating, thereby connecting the metallic pad and the thin metallic plate electrically to each other. Thereby, the desired portions of the suspension can be grounded through this simple structure without adopting a complicated structure wherein additional special lines for grounding are not separately laid besides the lines, which are lines for connecting a magnetic head and a control circuit board to each other.
