Patent ID: 8257094

Claim:
A connection terminal, comprising: a signal terminal that connects signal lines between a first multilayer substrate and a second multilayer substrate, the signal terminal including: a first end portion to be connected on a surface of a first layer of the first multilayer substrate, and a second end portion to be inserted into a first insertion hole of the second multilayer substrate to connect to a second layer of the second multilayer substrate; a ground terminal that connects ground lines between the first multilayer substrate and second multilayer substrate, the around terminal including: a third end portion to be connected on a surface of a third layer of the second multilayer substrate, the third layer facing the first layer of the first multilayer substrate, and a fourth end portion to be inserted into a second insertion hole of the first multilayer substrate to connect to a fourth layer of the first multilayer substrate; and an insulating holding medium that holds the signal terminal and ground terminal in a pair, with a specified distance therebetween.
