Abstract
Provided is a pressure detection device including: a pressure sensor including a pressure detection surface for detecting a pressure of a fluid; and a flow channel unit having a flow channel formed therein to guide the fluid to the pressure detection surface. The flow channel unit includes a flow channel body having the flow channelformed therein, and an earth ring disposed in contact with the pressure sensor. The earth ring is formed of a conductive fluororesin material including a fluororesin material and a conductive material in which the fluororesin material is dispersed, and is maintained at a ground potential.
