Abstract
Provided is a flow rate adjustment device including: a valve body portion configured to be movable along an axis line; a body portion having a valve bore and an upstream-side fluid chamber formed therein, the valve body portion being inserted into the valve bore, the upstream-side fluid chamber being configured to circulate a fluid; and a thin film-like first diaphragm portion which is coupled to the valve body portion and configured to isolate the upstream-side fluid chamber from a spring accommodation chamber adjacent to the upstream-side fluid chamber. The first diaphragm portion is formed of a conductive fluororesin material including a fluororesin material and carbon nanotubes dispersed in the fluororesin material, and the conductive fluororesin material has a volume resistivity of more than 1.0×10Ω·cm and less than 1.0×10Ω·cm.
