Claim 3:
4. A woven fabric with a photovoltaic power generation portion, comprising:
a plurality of warp yarns; and
a plurality of weft yarns,
wherein at least two weft yarns of the plurality of weft yarns are functional yarns comprising a first functional yarn and a second function yarn,
wherein each of the first and second functional yarns includes a photovoltaic power generation portion, a positive electrode conductive wire material connected to a positive electrode of the photovoltaic power generation portion, and a negative electrode conductive wire material connected to a negative electrode of the photovoltaic power generation portion,
wherein the first functional yarn and the second functional yarn are arranged away from each other in a warp direction, and the first and second functional yarns are arranged such that the positive electrode conductive wire material of one of the first and second functional yarns and the negative electrode conductive wire material of the other of the first and second functional yarns are arranged on a same side in a weft direction with respect to the photovoltaic power generation portion,
wherein a first conductive yarn configured as a warp yarn of the plurality of warp yarns is arranged, the first conductive yarn being in electric contact with the positive electrode conductive wire material of the first functional yarn and in electric contact with the negative electrode conductive wire material of the second functional yarn,
wherein a second conductive yarn configured as another warp yarn of the plurality of warp yarns is arranged, the second conductive yarn being in electric contact with the negative electrode conductive wire material of the first functional yarn and in electric contact with the positive electrode conductive wire material of the second functional yarn, and
wherein one of the first conductive yarn and the second conductive yarn is electrically disconnected in an area corresponding to between the first functional yarn and the second functional yarn, and the photovoltaic power generation portion of the first functional yarn and the photovoltaic power generation portion of the second functional yarn are connected in series.
