Patent ID: 8835767

Claim:
A suspension board with circuit comprising: an insulating base layer; and a conductive pattern that is laminated on a top surface of the insulating base layer, wherein the conductive pattern includes: a wire, and a terminal portion that is connected to the wire for being joined by a melted metal, wherein the insulating base layer, when viewing a sectional cut taken in a thickness direction which is perpendicular to a lengthwise direction and a widthwise direction of the suspension board with circuit, includes: a recess disposed in a bottom surface of the insulating base layer so as to form an adjacent region that is adjacent to the terminal portion, and a separated region that is separated from the terminal portion so as to sandwich the adjacent region between the terminal portion and the separated region, wherein the adjacent region is formed to be thinner than the separated region in the thickness direction, and wherein at least one lateral edge portion of the thinner adjacent region protrudes beyond an outermost lateral edge of the conductive pattern in the lengthwise direction of the suspension board with circuit.
