PROBLEM TO BE SOLVED: To provide an imaging unit that reduces light reflected upon a surface located on an imaging direction side further than an imaging lens and to be incident upon the imaging lens, and can suppress occurrence of ghosts and flares in a photographed image, and to provide a vehicle windshield and vehicle that include the imaging unit.SOLUTION: An imaging unit 100 comprises: an imaging device 110 that includes an imaging lens 112; a housing 120 that accommodates the imaging device 110, and includes an opening part 130 transmitting light to be incident upon the imaging lens 112; and an extension part that extends from the opening part 130 to a photographing direction N of the imaging device 110. The extension part includes an extension surface that has a scattering part 136 allowing a structure body to scatter light provided. Each of the structure body inclines in the photographing direction N relative to an axis vertical to the extension surface, and has a surface structure that includes an optical axis L of the imaging lens 112, and reflects the light parallel with a first vertical surface vertical to the extension surface in at least two mutually different oblique directions relative to the first vertical surface, when viewing the extension surface in a plane view.SELECTED DRAWING: Figure 1
【課題】撮像レンズよりも撮像方向側に位置する面によって反射されて撮像レンズに入射する光を減少させ、撮像された画像におけるゴースト、フレアの発生を抑制できる撮像ユニット並びにこれを備える車両用のフロントガラス及び車両を提供する。【解決手段】撮像ユニット100は、撮像レンズ112を有する撮像装置110と、撮像装置110を収納し撮像レンズ112に入射する光を通過させる開口部130を有する筐体120と、開口部130から撮像装置110の撮像方向Nに延びる延出部と、を備える。延出部は構造体によって光を散乱する散乱部136が設けられた延出面を有する。構造体のそれぞれは、延出面に垂直な軸に対して撮像方向Nに傾き、撮像レンズ112の光軸Lを含み延出面に垂直な第1の垂直面に平行な光を、延出面を平面視した場合に、少なくとも2つの互いに異なる、第1の垂直面に対して傾いた方向に反射する表面構造を有する。【選択図】図1
