PROBLEM TO BE SOLVED: To provide a sampling device of radioactive solution capable of sampling a trace amount of sample of the radioactive solution having a slurry shape or the like, while securing representativeness, because a sampling needle may be clogged in a sampling device using the sampling needle, when sampling a trace amount of radioactive solution having a slurry shape or high viscosity. SOLUTION: A valve element 12 wherein a communicating path 13 is formed is stored rotatably in a valve casing 11, and the communicating path 13 is positioned on a communication position agreeing with an inlet path 11a and an outlet path 11b formed in the valve casing 11 and on a sampling position agreeing with a cylinder 14a, a guide cylinder 14b and a sub-cylinder 14c of a cylinder head part 14 mounted in the valve casing 11. A jug holder 15 is provided on an outside part of the sub-cylinder 14c to enable mounting/dismounting of a jug 16, and a piston 17 sliding in the cylinder 14a can be inserted into/extracted from the communicating path 13 and the sub-cylinder 14c, to thereby push out the sample remaining in the communicating path 13 into the jug 16.
