Suspension assembly and disk drive

A suspension assembly comprising:

• a support plate;
• a head supported by the support plate;
• and
• a wiring member provided on the support plate, and constituted by a stacked layer body including a first insulating layer, a conductive layer provided on the first insulating layer to form wirings and a connection terminal, and a second insulating layer formed to overlap with the conductive layer and the first insulating layer, wherein
• the wiring member includes a distal portion electrically connected to the head, a connection end portion extending to an outside of the support plate, and wirings extending between the distal portion and the connection end portion, and
• the connection end portion includes an opening extending in a first direction and penetrating the first insulating layer and the second insulating layer, connection terminals formed by the conductive layer and arranged in the first direction in the opening, and a partition provided at the connection terminal in the opening to protrude toward the side of the second insulating layer from the connection terminal beyond the second insulating layer.
