PROBLEM TO BE SOLVED: To enable a center coordinate of a microlens to be highly accurately detected.SOLUTION: A microlens array 12 for a solid state image pickup element comprises: a plurality of microlenses that is provided in a photograph microlens area 130, and forms a two-dimensional image; and a state detection part 121. The state detection part 121 is configured to be provided in an outer peripheral part of the photograph microlens 120 area. The state detection part 121 is configured to generate an image in a smaller diameter than an image formed by the microlens 120 in an image formation plane where an image by the plurality of microlenses 120 is formed. 【課題】マイクロレンズの中心座標をより高精度に検出可能とする。【解決手段】固体撮像素子用のマイクロレンズアレイ１２は、撮像マイクロレンズ領域１３０に設けられ、２次元像を結像する複数のマイクロレンズ１２０と、状態検出部１２１とを備える。状態検出部１２１は、撮像マイクロレンズ１２０領域の外周部に設けられる。状態検出部１２１は、複数のマイクロレンズ１２０による像が結像する結像面においてマイクロレンズ１２０が結像する像よりも小さい径の像を生成する。【選択図】図１２
