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.
