Abstract: An electric wire capable of reducing an AC resistance equal to or less than the copper wire. In the electric wire in a single layered structure having a first layer of a substance having lower conductivity than copper, a radius of the wire is less than a skin depth, and an alternating current resistance value of the wire at a frequency used in the wire is greater than or equal to a sum of a direct current resistance value of the wire and a direct current resistance value of a copper wire having a same shape and a same outer diameter as the wire, and less than or equal to an alternating current resistance of the copper wire.

Abstract: The present invention provides a time delay device which allows changing, in accordance with a frequency of a local signal, a delay in a radio frequency signal supplied to an antenna element and also allows reducing a degree of dependency of the delay on a radio frequency in a band which is used. Each of (i) dispersion caused by a first dispersion imparting filter which gives a delay to a first local signal and (ii) dispersion caused by a second dispersion imparting filter which gives a delay to an intermediate frequency signal generated from the first local signal and the radio frequency signal is set to have a positive or negative sign which is opposite to the sign of the other.
