PROBLEM TO BE SOLVED: To provide a fluorescence imaging device capable of acquiring a subject distance while suppressing an increase in the number of parts. SOLUTION: This fluorescence imaging apparatus 100 includes visible light illumination 3 and excitation light illumination 4, visible light Vis reflected by a subject P, and near infrared fluorescence IR emitted from a fluorescent agent Pa by excitation light EL. The image pickup section 5 for picking up the image, the image processing section 15 for obtaining the visible light image 17b and the fluorescence image 17a, the visible light illumination 3 and the excitation light illumination 4 are provided separately in the image pickup section 5 and projected onto the subject P. The subject distance WD between the subject P and the imaging unit 5 is acquired based on the projection light source 6 that emits the light SL and the image 18 of the projection light SL that is acquired by the image processing unit 15 and is obtained by the projection light source 6. The subject distance acquisition unit 16 for [Selection diagram] Figure 1【課題】部品点数が増加することを抑制しつつ、被写体距離を取得することが可能な蛍光イメージング装置を提供する。【解決手段】この蛍光イメージング装置１００は、可視光照明３と励起光照明４とを含み、被写体Ｐによって反射した可視光Ｖｉｓと、励起光ＥＬによって蛍光薬剤Ｐａから発せられる近赤外蛍光ＩＲとを撮像する撮像部５と、可視光画像１７ｂおよび蛍光画像１７ａを取得する画像処理部１５と、可視光照明３および励起光照明４とは別に撮像部５に設けられ、被写体Ｐに対して投影光ＳＬを照射する投影光光源６と、画像処理部１５によって取得された、投影光光源６による投影光ＳＬの画像１８に基づいて、被写体Ｐと撮像部５との間の被写体距離ＷＤを取得する被写体距離取得部１６と、を備える。【選択図】図１
