A coaxial connecting member (1) for transmitting radio-frequency signals between a first and a second circuit board (2, 3) includes an inner conductor (4), an outer conductor (5) and an insulating member (6) arranged between the inner conductor (4) and the outer conductor (5). The inner conductor (4) and/or the outer conductor (5) comprise a first and a second end section (7, 8) to interconnect the inner conductor (4) to the first and the second circuit board (2, 3). The first and the second end section (7, 8) are interconnected to each other by at least one elastically deformable transversal section (9) to compensate axial and/or lateral misalignment of the first and the second circuit board (2, 3) with respect to each other.
