摘要： A transducer in which electrical connections between electrode sheets and leading wires can be secured via an approach other than soldering or welding is provided. In a sheet body portion, a dielectric layer and a first electrode sheet are joined by a first main fusion layer formed of a fusion material. A first conductive portion of a first leading wire is fixed to the sheet body portion by a first clamp. The first clamp includes a plurality of first leg portions that penetrates the sheet body portion in a thickness direction, a first coupling portion that couples the proximal ends of the plurality of first leg portions and is disposed across the first conductive portion, and a plurality of first bent-back portions that is formed by bending the respective distal ends of the plurality of first leg portions and is locked with a second surface of the sheet body portion.

摘要： A surface material (30) is wrapped along a circumferential direction of a ring part (12) in a region of at least a portion of the ring part (12). In a state in which a foamed resin or an elastomer is die-molded, a cross-sectional shape of a planar surface orthogonal to an axial direction of the ring part (12) is formed to be a C shape or a U shape, and a parting line (36) is formed on an outer surface. In a state of being wrapped on the ring part (12), the parting line (36) is disposed on a surface facing the ring part (12).
