Abstract: A pressure sensitive sensor is composed of a pair of upper and lower electrodes sheets 1 and 2 disposed oppositely, a spacer 3 interposed between both of the sheets 1 and 2, and adhesives 4 and 5 between these electrode sheets 1 and 2 and spacer 3. In the spacer 3, a hole 31 is formed in a position of a contact portion 6. A diameter of this hole 31, convex portions 13 and a pressure sensitive electrode 22 are set in such a positional relationship that a peripheral portion of the hole 31 is overlapped between the convex portions 13 and the pressure sensitive electrode 22. Then, the adhesives 4 and 5 open more largely than the diameter of the hole 31 of the spacer 3 so as to be removed from the peripheral portion of the hole 31 on both surfaces of the spacer 3.
