Abstract

This present invention serves to simplify manufacture of a contactless data transmission device (50). This device (50) has an electrically insulating carrier (1), a circuit element arranged on the carrier (1) made from a continuous antenna conductor track (2) in the form of at least one spiral winding (4, 5, 6) and respectively one terminal contact (15, 16) at the ends thereof as well as an electronic component (3) with at least two contact points (11, 12) electrically connected with the circuit element. The electronic component (3) is placed in a mounting region (10) above the at least one spiral winding (4, 5, 6). The at least two contact points (11, 12) of the component (3) are electrically connected with a respective terminal contact (15, 16) of the antenna conductor track (2). At least one spiral winding (4, 5, 6) is branched outside the mounting region (10) between two respective branching points (7′, 7″; 8′, 8″; 9′, 9″) into at least two spiral winding branches (4′, 4″; 5′, 5″; 6′, 6″). The data transmission device (50) is a component part of a valuable and/or security document (100).
