PROBLEM TO BE SOLVED: To provide an opening detection sheet and an opening detection system capable of suppressing the number of wiring to minimum and detecting accurately opening of a storage part.SOLUTION: An opening detection system 100 comprises: an opening detection sheet 1; an opening detection module 2 for detecting opening of the opening detection sheet 1; a master unit 3 capable of communicating with the opening detection module 2; and a server device 4 for communicating with the master unit 3 through a network 5. The opening detection sheet 1 includes resistances 15X for opening detection, being connected to a storage part 10 in series, and constant connection resistances 15Y connected to the resistance for opening detection in parallel, the resistance for opening detection and constant connection resistance are one set, and these sets are connected in series.SELECTED DRAWING: Figure 4 |
