Abstract
A flow meter for measuring a flow rate of a fluid passing through a fluid passage is provided with a throttle structure disposed at the inside, and it is connected to the fluid passage. The fluid passes through a groove via expanded grooves formed on a surface of a substrate which constitutes the throttle structure. The flow rate of the fluid passing through the fluid passage can be measured by detecting pressures and temperatures of said fluid on an inflow side and an outflow side concerning the throttle structure.
