Abstract:
1. A suspension board with circuit, comprising: a metal supporting board; an insulating base layer provided on the metal supporting board; a conductive pattern provided on the insulating base layer; a piezoelectric element mounting portion for mounting thereon a piezoelectric element; and a slider mounting portion for mounting thereon a slider including a magnetic head, the slider mounting portion being movable with expansion/contraction of the piezoelectric element, wherein the conductive pattern is configured to be electrically connected to the piezoelectric element, the piezoelectric element mounting portion includes a junction wall having a facing portion placed on one side of a bonding agent for bonding the piezoelectric element to the piezoelectric element mounting portion in an expanding/contracting direction of the piezoelectric element so as to face the bonding agent, and at least one restraining portion placed to face the bonding agent in a widthwise direction of the suspension board with circuit, the widthwise direction being perpendicular to the expanding/contracting direction, and the facing portion is configured to be pressed by the bonding agent when the piezoelectric element bonded to the piezoelectric element mounting portion expands/contracts.
