Abstract: To provide a technique that enables the risk of contamination to be reduced. Provided is a microparticle measuring apparatus including at least: a relay unit that enables a flow path through which microparticles flow and a cleaning fluid storage unit to communicate with each other; a sheath fluid tube that causes the flow path and a sheath fluid storage unit to communicate with each other; and a cleaning fluid tube that causes the relay unit and the cleaning fluid storage unit to communicate with each other, in which the relay unit includes a first connector that can be connected to a joint portion on the sheath fluid storage unit side of the sheath fluid tube.
