Claim of US Patent No. 11,032,913

1. An elongated wired circuit board including a plurality of wires arranged in parallel,wherein the plurality of wires each includes
a first linear portion extending in a first linear direction,
a second linear portion having the same width as that of the first linear portion, disposed at one side in the first linear direction of the first linear portion, and extending in a second linear direction so as to have a predetermined angle ? relative to the first linear portion, and
a connection portion disposed between the first linear portion and the second linear portion, being continuous with the first linear portion and the second linear portion, and having a width narrower than that of the first linear portion,
the connection portion includes
a first side further extending from a first widthwise one end edge orthogonal to the first linear direction of the first linear portion along the first linear direction,
a second side further extending from the second widthwise other and edge orthogonal to the second linear direction of the second linear portion along the second linear direction, and
the second linear portion includes
a third side connecting the first side with the second widthwise one end edge of the second linear portion, and extending along the first-crossing direction crossing the first linear direction and the second linear direction, and
the first linear portion includes
a fourth side connecting the second side with the first widthwise other end edge of the first linear portion, and extending along the second-crossing direction crossing the first linear direction and the second linear direction,
length y2 and length W satisfy the relationship of 0 the length y2 extending from a second corner portion formed with the first widthwise one end edge of the second linear portion and the third side and reaching the first side along the first width direction, and
the length W being the first width of the first linear portion, and
the predetermined angle ? satisfy the relationship of
0
