PROBLEM TO BE SOLVED: To provide: a solar battery unit having good solar battery characteristics with solar battery cells arranged so that a bus-bar electrode is thinner than a wiring member in width; and a method for manufacturing such a solar battery unit.SOLUTION: A solar battery unit 1 comprises: solar battery cells 2; and wiring members 5 electrically connecting between the solar battery cells 2. The solar battery cells 2 are glued with the wiring members 5 by an adhesive member 6. The wiring members 5 are connected to bus-bar electrodes 11a and 11b of the solar battery cells 2. The bus-bar electrodes 11a and 11b are thinner than the wiring members 5 in width. The adhesive member 6 has a total light transmittance of 50% or larger. 【課題】バスバー電極の幅が配線部材の幅よりも細い太陽電池セルにおいて、良好な太陽電池特性を有する太陽電池ユニット及び太陽電池ユニットの製造方法を提供する。【解決手段】太陽電池ユニット１は、複数の太陽電池セル２と、太陽電池セル２同士を電気的に接続する配線部材５と、を備え、太陽電池セル２と配線部材５とが接着部材６で接着されて、配線部材５が太陽電池セル２のバスバー電極１１ａ，１１ｂに接続されている。そして、バスバー電極１１ａ，１１ｂの幅が配線部材５の幅よりも細く、接着部材６の全光線透過率が５０％以上となっている。【選択図】図３
