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.
