ABSTRACT:
A reaction cell is provided with a vessel-like cell main body and a circular piezoelectric/electrostrictive oscillator fixed to an outside of a bottom surface of the cell main body. The cell main body includes a circular bottom plate portion and a circumferential wall portion which rises from a circumferential edge of the bottom plate portion so as to thereby surround the bottom plate portion. The bottom plate portion and the circumferential wall portion are integrally formed from ceramics. A solution accommodation space is formed above the bottom plate portion and is partially enclosed by the circumferential wall portion. The piezoelectric/electrostrictive oscillator is concentrically adhered to the outside of the bottom surface of the cell main body.
