To observe a biological sample that contains a chemiluminescent substance producing chemiluminescence in a living state using a microscope. The microscope is provided with a light source for emitting control light for varying the state of the chemiluminescence, a demarcation unit for demarcating the irradiation pattern of the control light irradiating an observation surface of the biological sample, and a detector for detecting the chemiluminescence emitted from the biological sample.
