PROBLEM TO BE SOLVED: To provide a pressing force detection sensor which detects pressing force more reliably.SOLUTION: A pressing force detection sensor 1 includes a long piezoelectric sensor 11, a rectangular plate member 20, and a mounting member 30. The piezoelectric sensor 11 is formed by covering a piezoelectric film 110 held by detection electrodes 111, 112 with an outer covering section 30. The piezoelectric sensor 11 is arranged so that a longitudinal direction thereof is in parallel to a short direction of the plate member 20, near one longitudinal end of the plate member 20. The piezoelectric sensor 11 is mounted on the plate member 20 with the mounting member 30. A viscosity agent 31 and an adhesive 32 are used in the mounting member 30. An area of the piezoelectric sensor 11 with the piezoelectric film 110 formed thereon is stuck to the plate member 20 with the viscosity agent 31. An area without the piezoelectric film 110 is bonded to the plate member 20 with the adhesive 32. |
