SUBSTRATE FOR SUSPENSION, SUSPENSION, SUSPENSION WITH ELEMENT, AND HARD DISK DRIVE

摘要

PROBLEM TO BE SOLVED: To provide a substrate for suspension with improved design flexibility of a wiring layer.SOLUTION: A substrate for suspension comprises: a metal support substrate; an insulator layer; and a wiring layer,which are laminated in this order. The wiring layer includes a terminal part connected to an element or an external circuit board. The terminal part has a via part-containing terminal part that contains a via part penetrating through the insulator layer and connected to the metal support substrate in planar view. The via part-containing terminal part is connected to another wiring layer through a first metal support part, a jumper part, a second metal support part, and a second via part.
