<p>The present invention relates to a pressure sensor for a touch panel which can effectively prevent a touch input error. According to the present invention, the pressure sensor for a touch panel includes: a signal input member, wherein electric conductors are patterned in the shape of fingers interdigitated on a substrate; a spacer which is disposed on the edge where the pattern of the electric conductors is not patterned on the substrate of the signal input member; and a piezo film which is disposed on the spacer by being apart from the signal input member, wherein a resistant value thereof changes according to the size of the applied pressure. A distance (D1) of the pattern of the electric conductors of the signal input member disposed adjacent to the spacer is shorter than a distance (D2) of the pattern of the electric conductors of the signal input member disposed farthest away from the spacer.</p> |
