Abstract
Abstract A modular jack to be mounted on a circuit board, the modular jack having contactors which will come into contact with a plug and terminals which will be connected with printed wires on the circuit board. The contactors and the terminals are stamped out of a hoop and fixed in a body case of the modular jack. An end of the contactors and an end of the terminals are arranged nearby, and filter elements for eliminating noise are disposed between the nearby ends.
