A flexure includes a metal base, a circuit member, and an actuator. The circuit member includes a base insulating layer, a conductor layer, and a cover insulating layer. The conductor layer includes a second pad, and a reference hole, which is an example of a portion to be protected, in a tongue portion. A second end portion of the actuator is fixed to the second pad via an adhesive. The circuit member includes a wall portion. The wall portion is formed between the second pad and the reference hole. A height of the wall portion is greater than a height of the second pad.
