PROBLEM TO BE SOLVED: To provide an oral cavity imaging device having a fisheye lens that can image all teeth of the upper jaw and the lower jaw simultaneously, and prevent an illumination light from being reflected on the fisheye lens directly.SOLUTION: An oral cavity imaging device 100 includes an imaging part 101, an operation part 102, and a neck-shaped support part 103. The imaging part 101 includes two fisheye lenses 104 and 104 disposed so that the back faces are opposed to each other, a housing 105 for supporting the two fisheye lenses 104 and 104, and an LED mounted on the side face of the housing 105. The imaging part 101 is inserted into the oral cavity and the LED of the imaging part 101 is caused to turn on for imaging.SELECTED DRAWING: Figure 1【課題】魚眼レンズを有する口腔内撮影装置において、上顎および下顎の全ての歯を同時に撮影できるようにするとともに、照明光が直接魚眼レンズに写り込まないようにする。【解決手段】口腔内撮影装置１００は、撮像部１０１と、操作部１０２と、首状の支持部１０３とを有する。撮像部１０１は、背面が対向するように配置された二つの魚眼レンズ１０４，１０４と、二つの魚眼レンズ１０４，１０４を支持する筐体１０５と、筐体１０５の側面に実装されたＬＥＤとを有する。撮像部１０１を口腔内に挿入し、撮像部１０１のＬＥＤを点灯させて撮影する。【選択図】図１
