Abstract

An air mass sensor has a three-part configuration formed of an insertion element, a measuring channel element and a housing element for accommodating an evaluation device. In order to be able to provide flexible insertion elements for a device having a short overall height, the measuring channel element and the housing element are joined to one another along a side of the measuring channel element that is perpendicular to the main direction.
