摘要:
A dummy trace portion is provided in a region between at least a suspension board with circuit on one end side and a support frame of a suspension board assembly sheet with circuits. A base insulating layer is formed on a support substrate in the dummy trace portion. A plurality of conductor traces are formed on the base insulating layer, and a cover insulating layer is formed on the base insulating layer to cover each conductor trace. At least one of the base insulating layer and the cover insulating layer in the dummy trace portion has a groove.

A plurality of suspension boards and an inspection substrate are integrally supported by a support frame. In each suspension board, a line is formed on a conductive first support substrate via a first insulating layer. The first support substrate and the line are electrically connected by a first via in the first insulating layer. In the inspection substrate, a conductor layer is formed on a conductive second support substrate with a second insulating layer sandwiched therebetween. The second support substrate and the conductor layer are electrically connected by a second via in the second insulating layer. The first via and the second via have the same configuration.
