Summary:To suppress destruction of a compound semiconductor solar cell.SOLUTION: A substrate 1 for growing a compound semiconductor solar cell is provided with a first orientation flat portion 2a and a second orientation flat portion 2b facing the first orientation flat portion 2a in a part of the periphery of a substrate 1. A first OF unit 2a and a second OF unit 2b are positioned to face each other in parallel. The length of at least one of the first OF section 2a and the second OF section 2b can be 16 mm or more.SELECTED DRAWING: Figure 1 【課題】化合物半導体太陽電池の破壊を抑制する。【解決手段】化合物半導体太陽電池成長用基板１は、基板１の周縁の一部に、第１のオリエンテーションフラット部２ａと、第１のオリエンテーションフラット部２ａと向かい合う第２のオリエンテーションフラット部２ｂと、を備えており、第１のＯＦ部２ａおよび第２のＯＦ部２ｂは互いに平行となるように向い合って位置している。第１のＯＦ部２ａおよび第２のＯＦ部２ｂの少なくとも一方の長さは、１６ｍｍ以上とすることができる。【選択図】図１
