Patent ID: 8519272

Claim:
A suspension substrate, comprising a metal supporting substrate, an insulating layer formed on the metal supporting substrate, and a wiring layer formed on the insulating layer; wherein in a connecting terminal area for connecting with a device, the wiring layer has a wiring layer projecting section projecting from an end portion of the metal supporting substrate and composing a connecting terminal; in the connecting terminal area, the insulating layer has an insulating layer projecting section projecting from the end portion of the metal supporting substrate and supporting the wiring layer projecting section; the wiring layer projecting section is provided by a plurality; an adjusting section formed on the insulating layer and composed of a first adjusting section and a second adjusting section is provided on both sides of the plural wiring layer projecting sections; and in a case when outermost wiring layer projecting sections of the plural wiring layer projecting sections are regarded as a first outermost wiring layer projecting section and a second outermost wiring layer projecting section respectively, a gap between the first outermost wiring layer projecting section and the first adjusting section, a gap between the adjacent wiring layer projecting sections, and a gap between the second outermost wiring layer projecting section and the second adjusting section are equal.
