Abstract
A housing defines a bypass passage and a sub-bypass passage therein. A bypass passage is configured to draw a part of an air flowing through a duct. The sub-bypass passage branches off the bypass passage and is configured to draw a part of air flowing through the bypass passage. A flow rate sensor is arranged in the sub-bypass passage and configured to generate an electric signal according to a flow rate of air in the duct by performing heat transfer with air passing through the sub-bypass passage. A physical quantity sensor is configured to measure a physical quantity of air in the duct. A sensor assembly is integrally formed with the flow rate sensor, the physical quantity sensor, and a circuit module. The circuit module includes a substrate that is configured to process signals from the flow rate sensor and the physical quantity sensor.
