Abstract
A wireless terminal cover is attached to a plate-like wireless terminal. The wireless terminal cover includes a bottom part that is in contact with the backside of the attached wireless terminal while covering the backside and is made of a dielectric having a relative dielectric constant of 1 to 10, wall parts that are in contact with the sides of the attached wireless terminal while surrounding the sides and are made of the dielectric, and a plurality of conductive elements placed in line on at least one of the bottom part and the wall part. The conductive elements are formed such that the length of the longest one of lines, each of which connects any two points on the conductive elements, is 0.1 to 0.4 times the effective wavelength of radio waves in the dielectric, the radio waves being used for radio communications by the wireless terminal.
