PURPOSE:To contrive not to unnecessarily generate crosstalks and noises by a method wherein a pad for external connection and reference potential has plural pieces, N pieces, of pads for external connection and reference potential, and pads for external connection and signal and the pads for external connection and reference potential are respectively arranged opposite mutually to the pads for external connection and reference potential and the pads for external connection and signal at a desired interval. CONSTITUTION:A pad GP for external connection and reference potential has plural pieces, N pieces, of pads GP1...GPN for external connection and reference potential corresponding to the N pieces of pads SP1...SPN for external connection and signal, and the pads SP1...SPN for external connection and signal and the pads GP1...GPN for external connection and reference potential have been successively arranged opposite to each other at the outer periphery part of a superhigh frequency integrated electronic circuit substrate 1 on the substrate 1 in such a way that the pad pair, wherein the pad SP1 for external connection and signal (however, i=1...N) and the pad GP1 for external connection and reference potential have been arranged opposite to each other at a desired interval, becomes the first pad pair P1 for external connection. Moreover, the pads GP1...GPN for external connection and reference potential have been mutually coupled by a wiring layer 4 formed on the superhigh frequency integrated electronic circuit substrate 1. |
