Abstract:
1. A connection structure between a coaxial connector and a multilayer board comprising: a casing; a coaxial connector provided in this casing, and including a core wire; a multilayer board provided in the casing, and including a first signal line pattern, an inner-layer pattern, and a pattern margin provided between an end face of the inner-layer pattern and an end face of the multilayer board; a transfer board provided in the casing located between the multilayer board and the coaxial connector, the transfer board including a second signal line pattern, a ground pattern, and a pattern margin provided between an end face of the ground pattern and an end face of the transfer board, and the transfer board formed so that the thickness of the transfer board is smaller than the thickness of the multilayer board; connecting means for electrically connecting the core wire of the coaxial connector and the second signal line pattern; and a transmission line that electrically connects the first signal line pattern to the second signal line pattern, and suppresses an electromagnetic field distribution in an inward direction of the multilayer board; wherein the pattern margin of the transfer board is smaller than the pattern margin of the multilayer board.
