A sampling valve comprises two fixed elements (10), (14), and a movable element (12) held between these fixed elements, in which a flow-in passage (Q) is provided at one fixed element so as to communicate with at least one of metering passages (P1), ..., plural flow-out passages (R1), (R2), ... are provided at the other or one fixed element so as to communicate with different metering passages individually, and relay passages (S1), ... are provided at the one or other fixed element so as to mutually connect the metering passages (P1), (P2), ... in specified combinations. In such constitution, plural sampling routes are formed in the sampling valve. In the sampling valve for aspirating and pushing liquid specimens such as blood in cylindrical shape and taking out quantitatively, only the portion necessary for measurement may be selected and sampled.
