Summary:An environment sensor is mounted on a second surface of a circuit board that does not have a wire bonding pad, and is arranged in a measuring chamber that is disposed in a circuit board receiving portion. The measuring chamber has a communication port for communication with a main passage. According to this configuration, process addition attributable to integration between a flow rate measurement device and the environment sensor is not required. The environment sensor does not affect air flow in a bypass passage, and thus detection accuracy of a flow rate detection element that is arranged in the bypass passage does not decline.
