This object aims to disclose a biological multi-directional observation device with measures to avoid an illumination backlight problem taken. In a preferable embodiment of the multi-directional observation device, a two-dimensional detector (6) is arranged right above a transparent specimen support (2) and a main image forming lens (8) is arranged right under the two-dimensional detector (6). A fluorescence-side filter (10) which allows only a fluorescence component from a biological specimen (4) pass therethrough is arranged, if necessary, between the main image forming lens (8) and the biological specimen (4). Reflection mirrors (M1, M2) are arranged on the down side of the specimen support (2), wherein the reflection mirrors are optional systems for leading a light of an image of the rear side of the biological specimen (4) to the main image forming lens (8). A light source device is provided to irradiate light to biological specimen (4). A light source in the light source device is set at a position that is not in direct and indirect viewing fields (16, 18) of the two-dimensional detector, so that the backlight problem is avoided and a vivid biological multi-directional observation image by the two-dimensional observation image by the two-dimensional detector can be acquired.
