Claim Text:
1. A measuring method for measuring characteristics of a specimen comprising: providing an aperture array structure having a specimen held thereto and having first and second principal surfaces, apertures, and a liquid directly or indirectly on at least a part of the first principal surface in a state open to an atmosphere under air pressure, wherein the apertures of the aperture array structure have a size which does not allow the liquid to leak from the first principal surface to the second principal surface, wherein the specimen is held on the aperture array structure, and wherein characteristics of the specimen change a place where the liquid is present on the aperture array structure, applying an electromagnetic wave to the aperture array structure from the second principal surface, the second principal surface being positioned on the opposite side to the first principal surface to which the liquid is attached, and detecting frequency characteristics of the electromagnetic wave reflected by the aperture array.
