To provide an optical element with suppressed optical noise.SOLUTION: The optical element includes a plurality of microlens arrays or fine convex mirrors (micromirror) as one example of curved portions curved to disperse light. The optical element, in the case where all of the plurality of curved portions are arrayed with regular intervals, comprises: a first irregular area 620 including an area where, with a center location of each of the plurality of curved portions as virtual point, directions in which apex positions of the curved portions are displaced from the virtual point are different between adjacent curved portions; and a second irregular area 630 in which relative positions of the apexes of the plurality of curved portions are same as relative positions of the apexes of the plurality of curved portions included in the first irregular area 620.SELECTED DRAWING: Figure 19

    【課題】光学的なノイズを抑制する光学素子を提供する。【解決手段】光を発散させるように湾曲する湾曲部の一例であるマイクロレンズアレイまたは微細凸ミラー(マイクロミラー)を複数備えた光学素子であって、複数の湾曲部の全てが規則的な間隔で配列された場合の、複数の湾曲部のそれぞれの中心位置を仮想点として、湾曲部の頂点の位置が仮想点からずれる方向が、隣り合う湾曲部の間で異なる領域を含む第一の不規則領域620と、複数の湾曲部の頂点の相対位置が、第一の不規則領域620に含まれる複数の湾曲部の頂点の相対位置と同じである第二の不規則領域630と、を含む。【選択図】図19
