Abstract: A sensor device is disposed in an intake passage through which intake air flows to an internal combustion engine. The sensor device includes a humidity sensor that generates a signal according to a humidity of the intake air flowing through the intake passage. A choke portion is defined in the intake passage to decrease a cross-sectional area of the intake passage. The humidity sensor is arranged on the choke portion.

Abstract: A physical quantity measurement device for measuring a physical quantity of a fluid includes a housing that includes a bypass flow channel through which a fluid flows and a physical quantity detection unit that detects a physical quantity of the fluid in the bypass flow channel. The housing includes a housing main body made of a dielectric and a covering film that covers at least a part of a surface of the housing main body, and the surface of the housing is positive charged due to positive charges being arranged in the housing main body along the surface of the housing main body or the positive charges being arranged in the covering film along a surface of the covering film.
