Flexure chain blank sheet for disk drive suspension

A flexure chain blank sheet for a disk drive suspension comprising a plurality of frame units, each of the frame units comprising:

• a frame portion made of a stainless steel plate;
• and
• a plurality of flexure elements arranged at a predetermined pitch within the frame portion, each of the flexure elements including a metal base formed of the stainless steel plate, a conductive circuit portion formed on the metal base, a distal end portion, and an extending portion extending from the distal end portion, wherein
• the frame portion comprises:
• a pair of lengthwise frames extending in a longitudinal direction of the flexure elements;
• a first lateral frame which extends in a width direction of the flexure elements and connects between tail portions of the respective flexure elements;
• and
• a second lateral frame formed of a distal end linking portion which is constituted by connecting between extending portions of the respective flexure elements, and
• the distal end linking portion comprises:
• first cut-off portions to be cut along the longitudinal direction between the extending portions which are adjacent to each other;
• and
