PROBLEM TO BE SOLVED: To provide a pressure sensitive sensor mat optimal for article theft prevention capable of certainly detecting whether an article is certainly placed on a mounting surface or the like by a plurality of pressure sensitive sensors, and to provide an article antitheft device excellent in a theft protection function of the article using this mat. SOLUTION: This pressure sensitive sensor mat has a dome shape having a circle in the plan view on the upper surface on one end side of a flexible printed wiring board having two parallel circuit patterns. The plurality of pressure sensitive sensors having a conductive elastomer layer whose electric resistance value is varied by deformation by pressing from the upside are arranged and fixed on a thin substrate at each certain interval, and are electrically interconnected in parallel. Thus, the article antitheft device can be alarm-displayed and is connected to the pressure sensitive sensor mat. COPYRIGHT: (C)2009,JPO&INPIT |
