Abstract
To provide a suspension board with circuit that enables its terminals to be bonded to the other terminals with sufficient strength with simple structure, to ensure sufficient bonding reliability, the suspension board with circuit 11 includes a suspension board 12, a base layer 13 formed on the suspension board 12, and a conductive layer 14 formed on the base layer 13 and a cover layer 18 with which the conductive layer 14 is covered, wherein external connection terminals 17 to be bonded to terminals 28 of a read/write board 29 are formed without the suspension board 12 and/or the base layer 13 being formed.
Claims4
