1. A microparticle measuring apparatus, comprising:
a relay unit configured to enable a flow path to communicate with a cleaning fluid storage tank,
wherein microparticles flow through the flow path;
a sheath fluid tube configured to cause the flow path to communicate with a sheath fluid storage tank; and
a cleaning fluid tube configured to cause the relay unit to communicate with the cleaning fluid storage tank,
wherein the sheath fluid tube having an end having a joint portion is directly connectable to a first connector of the relay unit, and the joint portion of the sheath fluid tube is also directly connectable to a side of the sheath fluid storage tank.
