ABSTRACT:
An intake-air control device for an internal combustion engine in which a sensor member can be positioned further accurately is provided. A throttle position sensor includes magnetic field generating means and a magnetic field detecting assembly. The magnetic field detecting assembly includes a plurality of terminal leads, a resin holder secured on the plurality of terminal leads, a sensor member generating a sensor output, and a resin mold body including the plurality of terminal leads, the holder, and the sensor member insert-molded. The resin holder includes a supporting surface which is located on a plane intersecting substantially perpendicularly to an axial line of a throttle shaft, and the sensor member includes a resin mold coat having first and second main surfaces opposing substantially in parallel to each other. The sensor member is held in the resin mold body with the first main surface of the resin mold coat in contact with the supporting surface.
