Abstract: There is provided technology that enables a microparticle sorting device to be adjusted highly accurately without using adjustment beads. The present technology provides a microparticle sorting device including a light detection unit that optically detects a microparticle flowing through a flow path, a droplet forming unit that forms a droplet containing the microparticle, and a device adjustment unit that adjusts the device, in which, in a process of adjusting the device before actual measurement of the microparticle, the device adjustment unit performs optical axis position calibration for calibrating a relative position of the flow path relative to irradiation light and delay time calibration for calibrating a delay time from light irradiation to the microparticle to formation of the droplet on the basis of information obtained from the microparticle to be measured.
