Abstract
A spectrum measuring device according to the present disclosure includes an accommodation part having a space for accommodating a culture solution containing a medium and cells, a light source device for irradiating a first surface of the space with excitation light, a light receiving device for receiving fluorescence occurring from the first surface, and an arithmetic device for spectral analysis of the fluorescence received by the light receiving device. In the space, the depth from the first surface of a fluorescence region where fluorescence is produced by incident excitation light is a value giving an internal shield of a prescribed level of less in the fluorescence region. The arithmetic device calculates the fluorescence spectrum of the cells by subtracting the fluorescence spectrum of the medium from the spectrum of the fluorescence of the culture solution obtained by the light receiving device.
