The invention discloses a steering wheel sensor with a human body detection function and a steering wheel. The steering wheel sensor comprises a sensing layer, a shielding layer and a spacing base material arranged between the sensing layer and the shielding layer. The sensing layer and the shielding layer are designed, the spacing base material is arranged between the sensing layer and the shielding layer, and the sensing layer and the shielding layer are oppositely and parallelly unfolded to form an existing plate capacitor structure. The sensing layer is used for recognizing touch and holding of the hands of a driver, the spacing base material forms a dielectric interval, and the shielding layer isolates electric signal interference of conductor devices such as a metal structure in a steering wheel rim framework and a heater layer below the shielding layer on the basis of the Faraday shielding effect principle. Therefore, the instantaneous stability of the potential is improved, and the hand holding effect of a driver is guaranteed.
