PROBLEM TO BE SOLVED: To provide an image pickup unit and an image pickup module that can be easily manufactured.SOLUTION: The image pickup unit includes: a cylindrical prism 33 having an incidence face 33b where light enters, a reflecting surface 33c that reflects the light entering from the incidence face 33b in a direction different from the incidence face 33b, and an emission face 33d that passes the light, which enters from the direction orthogonal to the incidence face 33b and is reflected by the reflecting surface 33c, straight therethrough and emits the same to the outside, and being approximate circular when viewed from the incident direction of the light an image pickup element 32 on a surface of which is formed a light-receiving part that receives light emitted from the emission face 33d and performs photoelectric conversion and a cylindrical image pickup holder 31 that protrudes from at least a portion of the perimeter of one end with a shape conforming to the side surface of the prism 33, prescribes the position of the incidence face 33b, and holds the prism 33.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡易に製造可能である撮像ユニットおよび撮像モジュールを提供すること。【解決手段】光を入射する入射面33bと、入射面33bから入射した光を入射面33bと異なる方向に反射する反射面33cと、入射面33bと直交する方向から入射し、反射面33cで反射された光を直進させて外部に出射する出射面33dとを有し、光の入射方向からみて略円をなす柱状のプリズム33と、出射面33dから出射された光を受光して光電変換する受光部が表面に形成された撮像素子32と、一端の少なくとも一部の外縁部からプリズム33の側面形状に応じて突出し、入射面33bの位置を規定してプリズム33を保持する円筒状の撮像ホルダ31と、を備えた。【選択図】図3
