PROBLEM TO BE SOLVED: To provide a dispensing apparatus capable of dispensing prescribed liquid and solid components while extracting/moving the solid component into other liquid in approximate synchronism with its dispensing operation. SOLUTION: The dispensing apparatus is composed of a component separating section and a pipette section 11. The component separating section includes an introducing channel 7 for introducing a first solution 6 containing solid particles 4, a flow channel 2 for introducing a second solution 9, concentration gradient generating means 3 for generating a concentration gradient of the solid particles 4 in the middle portion of the flow channel 2, and a lead-out channel 8 for leading out the first solution 6. The pipette section 11 is disposed so as to communicate with an end of the flow channel 2 from which the second solution 9 containing separated solid particles 4 moved from the first solution 6 into the second solution 9 by the concentration gradient generating means 3 is discharged.
