Zusammenfassung:PROBLEM TO BE SOLVED: To provide a solar battery module in which bonding strength of a wiring material is improved.SOLUTION: In a solar battery, a plurality of protruding parts 23 are provided on a first main surface which are provided at least on one side in a first direction y of a bus bar part 21b, with a wiring material 11 electrically connected to a first electrode 21. The protruding part 23 is provided at a position to overlap with the wiring material 11. The plurality of protruding parts 23 are provided such that a total of peripheral lengths including a finger part 21a, a bus bar part 21b, and the protruding part 23, in a region between adjoining finger parts 21a below the wiring material 11, is longer than a central part in a second direction of the first main surface at an end part in a second direction x of the first main surface. 【課題】配線材の接着強度が向上した太陽電池モジュールを提供する。【解決手段】第1の主面の上において、バスバー部21bの第1の方向yにおける少なくとも一方側に設けられている複数の凸部23を備え、第1の電極21に配線材11が電気的に接続される太陽電池であって、凸部23は、配線材11と重なるような位置に設けられている。配線材11の下方の隣接するフィンガー部21a間の領域における、フィンガー部21a、バスバー部21b及び凸部23を含めた周囲長の合計が、第1の主面の第2の方向xにおける端部において、第1の主面の第2の方向における中央部よりも長くなるように、複数の凸部23が設けられている。【選択図】図8
