Abstract
A respiratory air flowmeter includes a flow path forming member, a restricting portion, rectifying lattices, and a sensor. The flow path forming member forms a flow path in which respiratory air flows. The restricting portion and the rectifying lattices are arranged in the flow path in order to stabilize a respiratory air flow. The sensor is mounted in a sensor mounting portion of the flow path forming member, and detects a flow rate of respiratory air flowing in the flow path.
