THEFT PREVENTION SENSOR, THEFT PREVENTION SYSTEM AND THEFT PREVENTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a theft prevention sensor capable of preventing a theft with a simple structure.SOLUTION: Theft prevention sensors 14, 14B, 14C for detecting cutting of an adherend and preventing a theft includes vertical directional cutting detection parts 15B, 151-154, 155, 158 in which a thin line-like conductor is formed into a single brushstroke-like pattern, and when the adherend is cut in a vertical direction or a horizontal direction, the thin line-like conductor intersects with the vertical direction; and horizontal directional cutting detection parts 15B, 151-154, 156, 157 that intersect with the horizontal direction.
