Claim:
1. A suspension board assembly sheet with circuits comprising: a plurality of suspension boards with circuits; a support frame that integrally supports the plurality of suspension boards with circuits; and a plurality of inspection substrates provided to correspond to the plurality of suspension boards with circuits, wherein each of the plurality of suspension boards with circuits includes a conductive first support substrate, a first insulating layer formed on the first support substrate, a conductor line formed on the first insulating layer, and a first via that passes through the first insulating layer and electrically connects the first support substrate and the conductor line, each of the plurality of inspection substrates includes a conductive second support substrate, a second insulating layer formed on the second support substrate, a conductor layer formed on the second insulating layer and a second via that passes through the second insulating layer and electrically connects the second support substrate and the conductor layer, and the first via and the second via have the same configuration, wherein the plurality of suspension boards with circuits further include a third insulating layer formed on the first insulating layer such that at least part of the conductor line and the first via are covered, and the inspection substrate further includes a fourth insulating layer formed on the second insulating layer such that the second via is covered and at least part of the conductor layer is exposed.
