<P>PROBLEM TO BE SOLVED: To provide a simple and inexpensive electromagnetic wave sensor selectively and highly sensitively detecting only the millimetric waves and the submillimetric waves of prescribed frequencies, and to provide an imaging element, and an imaging device. <P>SOLUTION: This electromagnetic wave sensor 100 is formed so that spaces of openings between a plurality of antenna elements 121 are smaller than the wavelengths of infrared light. A capacitor electrically, formed out of openings between the plurality of antenna elements, and an electrical resistance part 111 together form a parallel circuit electrically connected to an antenna part 120. The plurality of antenna elements are formed so that impedance matching is obtained for the antenna part with the parallel circuit as to electromagnetic waves having the prescribed frequencies, while impedance matching is not obtained with respect to the higher harmonics of the electromagnetic waves having the prescribed frequencies. <P>COPYRIGHT: (C)2008,JPO&INPIT |
