To provide an electrostatic capacity sensor capable of ensuring higher detection accuracy.SOLUTION: An electrostatic capacitance sensor 50 includes a sensor electrode 41 having a pair of parallel electric wire portions 40a and 40b and a floating metal body 51 electrostatically coupled to the electric wire portions 40a and 40b. Further, the floating metal body 51 has an inter-wire arrangement portion 52 arranged between the pair of electric wire portions 40a and 40b. In addition, the inter-wire arrangement portion 52 has a dimension D1 of a thickness direction orthogonal to an arrangement positioning surface α of each of the electric wire portions 40a and 40b that is larger than a dimension D0 of each of the electric wire portions 40a and 40b in its thickness direction.SELECTED DRAWING: Figure 5
