Abstract
A steering wheel includes an annular rim portion, a boss section, one or more spokes interconnecting the rim portion and boss section, and a core member interconnecting these portions, the core member including a wheel portion disposed in the rim portion. The steering wheel further includes a cladding layer disposed around the wheel portion, a skin layer disposed on a front surface of the rim portion, and a sensor layer disposed between the cladding layer and the skin layer for detecting the driver's grip. The sensor layer includes a sheet-shaped substrate having stretch properties, a sensor composed of a conductive ink having stretch properties and applied to a front surface of the substrate, and an insulation sheet covering the sensor and having stretch properties. The sensor layer is generally formed into an annular band and mounted on an outer circumferential portion of the cladding layer by being stretched and expanded.
