This pressing sensor (10) comprises: a flexible film (30) including flat film parts (11, 12) that oppose one another, and a film fold-back part (31) that connects the flat film parts (11, 12) in a folded-back state, the flexible film being provided with a slit (32), along with the film fold-back part (31), on a fold-back line (FL) between the flat film parts (11, 12); and a flat piezoelectric film (17) that is bonded between the flat film parts (11, 12). The film fold-back part (31) is provided on the fold-back line (FL) at a distance from respective edges of the flat film parts (11, 12), or extends so that the longitudinal direction thereof is along a direction that intersects with the fold-back line (FL). Alternatively, the film fold-back part is partially exposed, on the surface where a wiring line part (23) is provided, from a cover material (33) that covers the wiring line part (23). |
