PROBLEM TO BE SOLVED: To provide an attachment plug coming-off detection device which can be easily mounted to various attachment plugs communicating to a power supply cable, is low-priced and improves detection accuracy of coming-off detection.SOLUTION: An attachment plug coming-off detection device 1 is configured to detect a state of connection between a plug receptacle 8 which receives power supply or supplies power, and an attachment plug 6 which is connected to the plug receptacle 8 and communicates to a power supply cable 5. The device 1 comprises at least: an induction part 2 which is abutted with a side of the plug receptacle 8 and inducts a state of connection between the plug receptacle 8 and the attachment plug 6 as positional information; a detection part 3 for detecting positional information from the induction part 2; and a display part 4 for displaying a detection result detected by the detection part 3. The device 1 is characterized in that the induction part 2, the detection part 3 and the display part 4 are integrally provided in the attachment plug 6. |
