Abstract
A suspension board with circuit includes a metal supporting board, a conductor layer having a terminal capable of being electrically connected to the piezoelectric element and disposed above the metal supporting board at spaced intervals thereto, a first insulating layer disposed between the metal supporting board and the conductor layer so as to support the conductor layer, and a second insulating layer disposed on the first insulating layer and the conductor layer so as to expose the terminal. The first insulating layer includes a first portion including the terminal viewed from a thickness direction of the metal supporting board and a second portion disposed in a position different from that of the first portion viewed from the thickness direction. The thickness of the first portion is thinner than that of the second portion.
