Abstract: A circuit member includes a metal base, an insulating layer, a conductor, and a cover layer. A termial portion of the circuit member includes a thick portion formed at a part of the insulating layer, a conductor convex portion which is a part of the conductor, and overlaps the thick portion, and a conductor extending portion. By the conductor convex portion and the conductor extending portion, a stepped side pad is formed. The stepped side gad includes a first surface along the conductor extending portion, and a second surface which rises in a thickness direction of the conductor extending portion. The stepped side pad and an element are connected by a conductive member.

Abstract: A flexure chain blank sheet includes a plurality of frame units. Each of the frame units includes a frame portion, and a plurality of flexure elements arranged within the frame portion. The frame portion includes lengthwise frames extending in a longitudinal direction of the flexure elements, and lateral frames extending in a width direction of the flexure elements. A slit that extends along the lateral frames, a connection portion, and recesses are formed between adjacent frame units. An opening width of the recesses is greater than an opening width of the slit. The connection portion includes a portion-to-be-cut which is to be cut by a cutter. The recesses allow insertion of the cutter.

Abstract: A first terminal provided on a tail pad portion includes a base portion, a bent portion and an overlapping portion. The base portion includes a first surface fixed to a base insulating layer and a second surface on an opposite side to the first sur face. The bent portion is reversed in a thickness direction of the base portion from an end of the base portion towards the second surface. The overlapping portion extends from the bent portion in a direction along the second surface. An ansotropic conductive film (ACE) is disposed between the overlapping portion and the second terminal. The overlapping portion and the second terminal are connected to each other via the ACE.
