Pressure type flowmeter and fluid control device

Abstract

A pressure type flowmeter includes a fluid resistance element provided in a flow path through which fluid flows, and in which a resistance flow path communicating with the flow path is formed, an upstream-side pressure sensor that detects upstream-side pressure of the fluid resistance element, and a downstream-side pressure sensor that detects downstream-side pressure of the fluid resistance element, in which the fluid resistance element is sandwiched and fixed by a pair of sandwiching components sealing components having a sheet-like shape are provided between the fluid resistance element and the sandwiching components and protrusions that partially press the sealing components are formed on at least one of the fluid resistance element and the sandwiching components.
