A particle analyzer includes a flow cell for enclosing a sample liquid containing particles in a sheathed flow to form a flat flow of the sample liquid; an exciting light source for emitting light for exciting fluorescence to irradiate the particle in the flat flow; a capturing device for capturing a fluorescent image of the particle when the particle reaches a predetermined position of the flat flow, the exciting light source and the capturing device being disposed so that a capturing optical axis of the capturing device is perpendicular to a surface of the flat flow and orthogonal to a light emitting optical axis of the exciting light source; and a shutter device for allowing the capturing device to receive the fluorescence from the particle for a predetermined period of time.
