PROBLEM TO BE SOLVED: To provide: a solar battery unit having good solar battery characteristics with solar battery cells arranged to be connected to wiring members via no bus-bar electrode; 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. Each solar battery cell 2 is bonded to the wiring member 5 by an adhesive member 6 via no bus-bar electrode 11 at least on the side of a light-receiving surface 2a of the solar battery cell 2. The adhesive member 6 has a total light transmittance of 50% or larger. According to this embodiment, light reaching under each wiring member 5 will be incident on the light-receiving surface 2a of the solar battery cell 2 underlying the wiring member 5, contributing to power generation and therefore, the solar battery characteristics can be enhanced. 【課題】バスバー電極を介することなく配線部材と接続される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、少なくとも太陽電池セル２の受光面２ａ側において、太陽電池セル２は、バスバー電極１１を介することなく接着部材６によって配線部材５に接合され、接着部材６の全光線透過率が５０％以上である。これにより、配線部材５下に回りこんだ光が、配線部材５下の太陽電池セル２の受光面２ａに入光して発電に寄与するため、太陽電池特性を向上させることができる。【選択図】図３
