(57) [Abstract] To provide a cable checker to verify the connector of the multi-core cable having a connector for Objective end. [Configuration] The voltage input means 4 for inputting a test voltage to each the pin to one of the connectors of the multi-core cable has a connector that matches the other connector of the multi-core cable, And the wiring unit 5 for transmitting the connector pin position signal When a connector pin position display unit 6 to enter the connector pin position signal from the wiring unit, an address converting unit 7 to obtain a pin address signal corresponding to the connector pin position signal, and displays the output of the address converting unit It has a connector pin address display unit 8. [Effect] does not require proficiency in the operation and can be performed by the operator quickly reliable person check the connector.
