PROBLEM TO BE SOLVED: To provide a printed circuit board assembly that can transmit signals having very high frequency data through the printed circuit board assembly. SOLUTION: A printed circuit board assembly 10 has a pair of printed circuit boards 12, 14, where the printed circuit boards 12, 14 have conductor vias 22 passing through from a surface of a dielectric 16 to an inner area 17 of the dielectric 16, and have a reference potential layer 20 and a signal conductor placed parallel to the reference potential layer 20, to form a transmission line having a predetermined impedance. In the printed circuit board assembly 10, a first electrical connector 34 having signal contacts 38 respectively coupled to the conductor vias 22 of the one board 12 is formed, and a second electrical connector 32 having signal contacts 36 respectively coupled to the conductor vias 22 of the other board 14 is formed. The first signal contacts 38 of the first electrical connector 34 are arranged so as to be respectively coupled to the second signal contacts 36 of the second electrical connector 32.
