SUBSTRATE UNIT FOR SIGNAL TRANSMISSION AND ITS MANUFACTURING METHOD, CONNECTOR, AND COMMUNICATION DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a communication device wherein a substrate unit for signal transmission and a communication element are configured as separate bodies.

SOLUTION: The substrate unit 14 has a multilayer structure comprising a first signal transmission layer 20 and a power layer 44 and/or a second signal transmission layer 30 as a ground layer. The substrate unit 14 has an opening into which a connector 222 is to be inserted. The opening is formed in the form of steps. The outer shape of the connector 222 is also in the form of steps in accordance with the shape of the opening. Due to this structure, electric connection between each layer and electrodes 224 of the connector 222 can be ensured.
