PROBLEM TO BE SOLVED: To reduce the number of terminals compared to the case of respectively detecting signals received by individual terminals, of a plurality thereof arranged in a given direction, the individual terminals located at both ends in the aforementioned direction.SOLUTION: A cable 14 has plural contacts arranged in a given direction. A connection part 12 has plural terminals to be connected one-to-one to the plural contacts. A power feed part 13 feeds power to an inspection part 21 of a second substrate 2, via the contact, from a power-feed terminal 121 (a first terminal) located at one end in a given direction, of the plural terminals. Power-fed, the inspection part 21 supplies an inspection signal to an inspection signal terminal 122 (a second terminal) located at the end on a side opposite to the power-feed terminal 121. A control part 11 detects a signal received by the inspection signal terminal 122. In the case of the signal detected by the control part 11 not meeting a predetermined condition, a notification part 3 notifies a user of an abnormal connection. |
