PROBLEM TO BE SOLVED: To provide a simple capacitance sensor capable of showing a function as a capacitance type proximity sensor in a high degree, as well as, functioning as a touch sensor. SOLUTION: Detection electrodes A, B for detecting a capacitance change, a shielding electrode S with an opening part facing a detection direction in order to restrict the detection range of the capacitance, and a ground electrode G are disposed in the longitudinal direction, and the detection electrodes A, B are disposed at a near position and a far position from the opening part in the shielding electrode S, and an electrode for contact detection is disposed on the back side to the detection direction of the shielding electrode. Each electrode is maintained in a separate state while in the natural state, and each electrode is connected in a body by a nonconductive flexible body so that when a sensor body 1 is pushed from the detection direction by contact of an object, the shielding electrode S and the grounding electrode G are brought into contact and become conducting, so that object contact is detectable.
