Abstract

A dispenser has a pressure sensor enabled to detect a pressure precisely by forming a pressure sensor integrally with a syringe constructing a nozzle to thereby eliminate a pipeline or the like. The dispenser is provided for sucking and discharging a liquid from a nozzle by slidably moving a piston sliding in the inside of a syringe by a motor mounted in a body. A detection sensor for detecting the internal pressure of the inside of the syringe is integrally formed by connecting its air inlet directly to a through hole formed to extend to the inner face of the syringe.
