Abstract
A flow rate measuring device includes: a flow rate sensor; a physical property sensor having a micro heater and a thermopile; and a sub-flow path portion having a physical property detecting flow path in which the physical property sensor is disposed. The micro heater and the thermopile are disposed side by side in a direction orthogonal to a flow direction of a fluid to be measured, and the flow rate sensor is disposed at a position except for the physical property detecting flow path.
