To provide an imaging device capable of obtaining an image suitable for observing an object containing a fluorescent material.SOLUTION: An imaging device comprises: a first light source 101 that irradiates an object including a fluorescent material with excitation light； a second light source 102 that irradiates the object with observation light having a wavelength longer than the fluorescence generated from the fluorescent material in response to the excitation light； an imaging unit 103 that obtains an image of the object by photographing light including the wavelength of the fluorescence and the wavelength of the observation light, excluding light of a predetermined wavelength or less including the wavelength of excitation light, in a state where the excitation light and the observation light are simultaneously radiated from the first light source and the second light source； and an output unit 104 that outputs the image acquired by the imaging unit 103.SELECTED DRAWING: Figure 1【課題】蛍光物質を含む対象物の観察に適した画像を得ることができる撮像装置等を提供する。【解決手段】蛍光物質を含む対象物に励起光を照射する第一の光源１０１と、励起光に応じて蛍光物質から発生する蛍光よりも長い波長の観察光を、対象物に照射する第二の光源１０２と、第一の光源および第二の光源から前記励起光と観察光とを同時に照射した状態で、励起光の波長を含む予め決められた波長以下の光を除外して、蛍光の波長および観察光の波長を含む光を撮影して、対象物の画像を取得する撮像部１０３と、撮像部１０３が取得した画像を出力する出力部１０４とを備えるようにした。【選択図】図１
