Claim Text:
1. A read sensor comprising: a dielectric plate that has a predetermined permittivity; conductive elements, that are provided on a first plane of the dielectric plate, and that, by receiving a supply of current, generate electromagnetic waves and acquire data from a read object in a non-contact manner; a metal plate that covers a second plane of the dielectric plate, which is a back plane of the first plane; and perturbation elements that are provided on the first plane and connected to the conductive elements, wherein: the conductive elements are formed with first elements of a linear shape and second elements of a linear shape, have a shape in which the first elements and the second elements are connected with each other, as if drawn unicursally in one stroke, so that an angle formed between a first element and a second element becomes a predetermined sharp angle, and acquire the data using a magnetic field or an electric field depending on a distance to the read object; the first elements and the second elements have current supply parts that connect with a device that supplies current, in edge parts of the first elements and the second elements in a long direction; and the perturbation elements are provided to extend between the first elements and the second elements, from side edge parts located between the current supply parts and centers of the first elements or the second elements having the current supply parts in the long direction, and match impedance in the current supply parts.
