PROBLEM TO BE SOLVED: To suppress reduction in color reproducibility caused by crosstalk among pixels.SOLUTION: The microlens with a filter array includes: a filter array including a plurality of first optical filters that selectively allow light in an infrared region to pass through and a plurality of second optical filters that selectively allow light in a first wavelength region contained in a visible light region to pass through; and a micro lens array including a plurality of microlenses respectively corresponding to plural kinds of optical filters. 【課題】画素間のクロストークによる色再現性の低下を抑制する。【解決手段】実施形態のフィルタアレイ付マイクロレンズは、赤外領域の光を選択して透過させる複数の第１の光学フィルタと可視光領域に含まれる第１波長領域の光を選択して透過する複数の第２の光学フィルタとを含むフィルタアレイと、複数種類の光学フィルタそれぞれと対応する複数のマイクロレンズを含むマイクロレンズアレイとを備える。【選択図】図８
