Abstract
A particle detector that includes an inspection light source that irradiates a flow cell with inspection light, the flow cell that allows a fluid containing a particle to flow therethrough, the flow cell including a semispherical reflective film that reflects reaction light generated by the particle irradiated with the inspection light, and a semispherical lens portion through which the reaction light reflected by the semispherical reflective film passes, an elliptical mirror that has a first focus at a position of the flow cell, and that reflects the reaction light having passed through the semispherical lens portion of the flow cell, and an optical detector that is disposed at a second focus of the elliptical mirror and that detects the reaction light reflected by the elliptical mirror.
