To provide a capacitance sensor capable of improving accuracy for determining contact or proximity, and also to provide a steering having this capacitance sensor.SOLUTION: A capacitance sensor 30 includes: a dielectric body 34; a sensor electrode 32; and a conductor 36. The sensor electrode 32 is arranged and installed on one surface of the dielectric body 34 and creates capacitance between an object (hand 50) in contact with or in proximity to the other surface of the dielectric body 34. The conductor 36 is arranged and installed on the other surface portion of the dielectric body 34 in opposite to the sensor electrode 32. Compared to an area S1 of an opposing face 36A on one end side of the conductor 36 near the sensor electrode 32, an area S2 of an opposing face 36B on the other end side of the conductor 36 far from the sensor electrode 32 is configured smaller. This conductor 36 is brought into a floated state.SELECTED DRAWING: Figure 5

    【課題】接触か近接かを判定する精度を向上させることができる静電容量センサ及びこの静電容量センサを有するステアリングを提供する。【解決手段】静電容量センサ30は誘電体34、センサ電極32及び導体36を備えている。センサ電極32は、誘電体34の一表面に配設され、誘電体34の他表面に接触又は近接する物体(手50)との間に静電容量を生じさせる。導体36は、センサ電極32に対向して誘電体34の他表面部分に配設されている。導体36のセンサ電極32に近い一端側の対向面36Aの面積S1に比し、導体36のセンサ電極32から遠い他端側の対向面36Bの面積S2が小さく構成されている。この導体36は、電気的に浮動状態とされている。【選択図】図5
