A WIM sensor for measuring wheel forces of vehicles on a road that pass over the sensor includes an elongated hollow profile along a longitudinal axis thereof. First and second inner pressing surfaces inside the profile are arranged connected in opposition on both sides by curved, pre-tensioned profile edges. Each of a plurality of piezoelectric measuring elements inside the profile has first and second force absorbing surfaces that face the first and said second pressing surface, respectively. Each of the measuring elements is disposed between two absorbing elements that exert a pretension thereon via the pressing surfaces. A long strip of insulating film provided with an electrically conductive layer on one of its sides electrically connects the first force absorbing surfaces of the measuring elements that are electrically insulated from the first pressing surface.
