Abstract:

A microparticle analysis device (1) is provided with a light source (16), a two-dimensional photoelectric conversion sensor (28), and a calculation unit (10C). The light source (16) irradiates a microparticle (M) flowing in a flow path (14C) with excitation light (L1). The two-dimensional photoelectric conversion sensor (28) receives fluorescence emitted from the microparticle (M) by a light receiving surface (30) including a plurality of light reception units (32) arranged two-dimensionally, and acquires data of a fluorescence signal including stored charge values of the plurality of light reception units (32), respectively. The calculation unit (10C) calculates an evaluation value including an area that is a total value of a plurality of stored charge values included in the data of the fluorescence signal.
