A toothed belt is provided which is made of an elastomeric material or the like and which comprises a plurality of teeth, alternating with spaces, covered with at least one layer of textile material. The elastomeric material forming the top of at least one tooth and the relative covering textile material layer are shaped to define at least one depression limited by two lateral protuberances. The seam joining the textile layer end portions is situated along the depression so that no rubbing can take place between the seam and a surface external to the belt. Preferably, the depression botton is formed to have a curvilinear shape and the ratio between the thickness 's' of the covering textile material layer and the bending radius 'r' of the depression bottom ranges between 0.1 and 10.0.
