PROBLEM TO BE SOLVED: To prevent decrease in self-purification effect due to a photocatalyst.SOLUTION: An imaging apparatus comprises: a first lens 3A whose surface is formed with a photocatalyst film; an imaging element 11 for taking an image formed by the first lens 3A; an ultraviolet light LED 21 that is housed in a camera housing 2 for holding the first lens 3A and emits ultraviolet light radiated to the first lens 3A; and a first light guide part 8 for guiding the ultraviolet light emitted by the ultraviolet light LED 21 to the back surface of the first lens 3A. 【課題】光触媒による自己洗浄効果の低下を抑制する。【解決手段】光触媒膜を表面に形成した第１レンズ３Ａと、第１レンズ３Ａによる像を撮像する撮像素子１１と、第１レンズ３Ａを保持するカメラ筐体２内に収納され、第１レンズ３Ａに照射される紫外光を発光する紫外線ＬＥＤ２１と、紫外線ＬＥＤ２１により発光された紫外光を、第１レンズ３Ａの裏面側に導光する第１導光部８とを備えている。【選択図】図１
