PROBLEM TO BE SOLVED: To provide a micromanipulation unit suitable for performing a non-contact type manipulation, and also to provide a micromanipulation system. SOLUTION: In the micromanipulation unit 10, a plurality of piezoelectric elements 14 are arranged aligning on the bottom face 12a of a liquid bath 12 taking a space between the bottom face 12a and an upper place of the bottom face of the liquid bath 12 as an extending/contracting direction. A liquid 18 containing particles 16 as a manipulation object is injected to the liquid bath 12, and a voltage is imparted to a specific piezoelectric element 14 to oscillates it. Through the movement of the liquid to the upper face of the specific oscillating piezoelectric element 14 or close to the upper face, therefore, the particles 16 entrained by the liquid are gathered. By sequentially moving the oscillating piezoelectric element 14, the gathered particles 16 are moved, and also another appropriate micromanipulation is suitably applied to the particles 16 moved to the predetermined position.
