PROBLEM TO BE SOLVED: To provide a weight detector for balancing weights of a plurality of objects and obtaining the weights of a plurality of the objects. SOLUTION: The weight detector includes a stem body 23 which is fixed to a support member 22 at one end and is free at the other end; a filtrate-holding section 24, a replacement liquid holding section 25 and a dialysis liquid holding section 26, disposed at three locations on the stem body 23 in the longitudinal direction, and holding the objects; first, second and third distortion detecting sections 27, 28 and 29, respectively for detecting distortions from the free end of the stem body 23 to the holding sections in the stem body 23, corresponding to the total weight of the objects held by the holding sections; and a weight calculating section 30 for calculating the weights and the total weight, based on an obtained detection result.
