: A coil body, in particular for RM cores, has sufficient mechanical stability and a high thermal stability, because of the following features: a) A hollow cylinder (1), together with a upper flange (2) and an lower flange (3), forms a coil winding core (4). b) on the lower flange (3) are fitted shoulders (5, 6) pointing outwards essentially radially, and having a thickness that is greater than that of the lower flange (3). c) The shoulders (5, 6) hold connecting pins (7) projecting from their undersides. d) Between every two shoulders (5, 6) there is a wire guide slot (8) opening on one side radially outwards, the closed end (9) of which terminates in the area of the lower flange (3) near the outer side of the hollow cylinder (1). e) At the closed end (9) a short section of the wire guide slot (8) is closed off by a filling shoulder (10), the upper side of which is stepped beneath the upper side of the lower flange (3). f) On their lower sides the shoulders (5, 6) are joined together by a bridge (13) crossing the wire guide slot (8), which extends along the under side of the filling shoulder (10) and is joined to it. g) The coil body is made of a duroplastic unsaturated polyester containing additives which improve its ability to be processed.
