Abstract
A pressure-sensing device including a pressed component that has a contact surface to which pressure is applied by contact from a presser; a polymeric piezoelectric element that is disposed at an opposite side from the contact surface of the pressed component and that has a piezoelectric constant dof 1 pC/N or more as measured at 25° C. using a stress-charge method; a curable resin layer that includes at least one selected from the group consisting of cold-setting resins, thermosetting resins, and actinic radiation-curable resins and that is in contact with at least part of a surface of the polymeric piezoelectric element; and an electrode that is in contact with at least part of a surface of the polymeric piezoelectric element or of a surface of the curable resin layer.
