<p>An operation fluid movement device (10) is a laminated body of ceramic sheets (11a-11c) that form a flow path (13). The ceramic sheet (11c) forms a film, and a piezoelectric/electrostrictive film (12) is integrally formed on the upper face of the ceramic sheet (11c). In the flow path (13), a first operation fluid (14) and a second operation fluid (15) are received. Wettability of the first operation fluid with respect to the inner wall face of the flow path is inferior to the wettability of the second operation fluid. When voltage is applied to the piezoelectric/electrostrictive film, the center portion of the ceramic sheet (11c) is bent and displaced to reduce the cross-sectional area of the flow path. The first operation fluid (14) in presence as a fluid mass in the center portion of the flow path is separated into two when the fluid receives repulsive force, caused by inferior wettability of the fluid, from the wall surface of the flow path, and moves in the flow path.</p> |
