PROBLEM TO BE SOLVED: To not only irradiate a prescribed area of a living body such as the hand with light by positioning the living body with respect to a surface light emitting part but also to facilitate processing after imaging such as comparing images obtained by an imaging part with each other.SOLUTION: The intravital observation device includes: a surface light emitting part 2 which has a light emitting surface 201 facing a living body placement area X and irradiates the living body in the living body placement area X with light a positioning member for positioning the living body with respect to the light emitting surface 201 of the surface light emitting part 2 and an imaging part 3 which has been positioned with respect to the light emitting surface 201 of the surface light emitting part 2, receives light transmitted by the living body in the living body placement area X, and outputs image data.COPYRIGHT: (C)2012,JPO&INPIT【課題】手等の生体を面発光部に対して位置決めすることによって、生体の所定領域に光を照射できるだけでなく、撮像部により得られた画像を比較する等の撮像後の処理を容易化する。【解決手段】生体配置領域Xを向く発光面201を有し、当該生体配置領域Xにある生体に対して光を照射する面発光部2と、前記面発光部2の発光面201に対して生体を位置決めする位置決め部材と、前記面発光部2の発光面201に対して位置決めされており、生体配置領域Xにある生体を透過した光を受光して画像データを出力する撮像部3とを具備する。【選択図】図1
