<P>PROBLEM TO BE SOLVED: To provide an inspection device which is capable of efficiently inspecting an electrical connection state of a new jumper wire. <P>SOLUTION: The inspection device includes: a first inspection terminal (6) to be grounded; a second inspection terminal (7) to be electrically connected to an end of a new jumper wire connected to a terminal-line-side terminal on the new exchange side; and an internal circuit (2) which is between the first inspection terminal (6) and the second inspection terminal (7) and is given a voltage barrier part (3) having a threshold voltage lower in absolute value than a feeding voltage. The internal circuit (2) includes: a first notification circuit for performing first notification when a voltage of the second inspection terminal (7) relative to the ground is changed to a voltage higher in absolute value than the threshold voltage; and a second notification circuit for performing second notification when the voltage of the second inspection terminal (7) relative to the ground is changed to a voltage lower in absolute value than the threshold voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
