PROBLEM TO BE SOLVED: To uniformly mix a plurality of different kinds of sample to the most extent so as to improve the mixing effect. SOLUTION: Liquids A, B and C within first and third containers 5, 7 and 9 are sucked into first and third supply passage respectively by driving a vacuum pump and they enter into a sample mixer 1. The liquid A is divided into first and third joint pointsαandγat a first dividing point a and they enter into a circular passage 3. The liquid B in a second container 7 and the liquid C in the third container 3 also move in the same manner as the liquid A. The liquids A and B entering toward the first joint pointαare mixed with each other at the first joint pointαprimarily, and enter into a first mixing passage 10. The other liquid moves in the same manner. A mixed liquid of the liquids A and B, a mixed liquid of the liquids B and C, and a mixed liquid of the liquids C and A which enter respectively into first and third sample mixing passages 10, 11 and 12, are mixed with each other at a fourth joint pointδ, and they enter into a fourth mixing passage 13. The liquids A, B and C are mixed with each other at the fourth joint pointδ.
