We fabricated micro-pump using stereolithography technology. The pump was fabricated using PZT for its drive and used non-movable valve of diffuser/nozzle concept. Size of the pump chamber is, $14mm{psi}$, narrow hole of diffuser/nozzle is $0.5mm{psi}$ and wide hole $1mm{psi}$ and chamber depth is 1.2mm, respectively. We confirmed its operation at frequency 100Hz, supply voltage $90{sim}250Vp-p$. As the result of the pump working measurement, when ethanol is used, the pressure head difference between inlet and outlet of the pump is about 53mm in the frequency of 100Hz, 200V of Vp-p.
