To provide a capacitive sensor having higher degree of freedom of installation than conventional ones.SOLUTION: A capacitive sensor comprises: a substrate; a first print electrode formed on a first surface of the substrate; a second print electrode formed on a second surface, on the opposite side to the first surface, of the substrate and larger in area than the first print electrode; a first drawing print wiring for applying voltage to the first print electrode; and a second drawing print wiring for applying voltage to the second print electrode. The substrate has one or plural first notch parts. The second print electrode has one or plural second notch parts. The first notch part is formed so as not to cut the first and second drawing print wirings.SELECTED DRAWING: Figure 3
