Abstract: 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.

Abstract: A flexure chain blank sheet includes frame units. Each frame unit includes a frame portion, and flexure elements. The flexure element includes a distal end portion, and an extending portion. The frame portion includes a pair of lengthwise frames and a pair of lateral frames. The first lateral frame connects between tail portions of the flexure elements. The second lateral frame is formed of a distal end linking portion which is constituted by connecting between respective adjacent extending portions. The distal end linking portion includes first cut-off portions to be cut along a longitudinal direction between the adjacent extending portions, and second cut-off portions to be cut along a width direction between the distal end portion and the extending portion.
