Abstract: The present disclosure provides a flow rate measuring device including a first chip, a second chip, and a holding body. The first chip and the second chip are disposed in an intake passage of an internal combustion engine. The first and second chips detect at least one of a flow rate of an intake air and a parameter other than the flow rate. The holding body holds the second chip and protrudes into an inside of the intake passage. The second chip is exposed inside of the intake passage in a state where the second chip is covered by a filter. The holding body includes a resin portion that forms a surface of the holding body. The portion of the filter is inserted into the resin portion. The recessed portion is recessed from a surface of the resin portion. A portion of a first surface of the filter defines a bottom of the recessed portion. The second chip is positioned on a side of a second surface of the filter that is opposite to the first surface.

Abstract: An airflow-rate detecting device capable of detecting humidity has a housing, a flow rate sensor, a humidity sensor, a humidity sensor case, and a dust separating portion. The housing therein defines a bypass passage into which a part of air flowing in a duct flows. The flow rate sensor is disposed in the bypass passage. The humidity sensor detects a humidity of air flowing in the duct at an outside of the housing. The humidity sensor case houses the humidity sensor and therein defines an interior space into which a part of air flowing in the duct flows as a target air of which humidity is detected by the humidity sensor. The dust separating portion removes dust from the target air before the target air flows into the interior space.
