Abstract
To provide a flow sensor having improved responsiveness compared to the prior art, the flow sensor of the present invention includes an insulation board, a flow-rate detection resistance element, and a temperature compensation resistance element. Each of the flow-rate detection resistance element and the temperature compensation resistance element is arranged on the insulation board such that a terminal temperature of the temperature compensation resistance element approaches a terminal temperature of the flow-rate detection resistance element. Accordingly, responsiveness can be improved.
