Abstract: PROBLEM TO BE SOLVED: To provide a communication connector which can control reduction in effect of removing high-frequency components in response to temperature change.SOLUTION: A communication connector 30 comprises a magnetic body 1 attached to connection terminals 3, 4, a magnetic-field forming member 2 which is attached to the magnetic body 1 and forms a magnetic field around the connection terminals 3, 4, and a control unit 5 which changes current to the magnetic-field forming member 2 depending on the temperature of the magnetic body 1. For example, when the temperature of the magnetic body 1 increases, the permeability of the magnetic body 1 will decrease, reducing the removal effect of a high-frequency component. On the other hand, as the communication connector 30 comprises the magnetic-field forming member 2 attached to the magnetic body 1 and the control unit 5, the control unit 5 compensates the lowering of characteristics of the magnetic body 1 due to temperature change with a magnetic field around the connection terminals 3,4 formed by the control unit 5 changing current to the magnetic-field forming member 2 depending on the temperature of the magnetic body 1. This can control reduction in removal effect of a high-frequency component.
