FIG. 4 is a configuration diagram illustrating the configuration of the antenna cover according to the first embodiment, and FIG. 5 is a cross-sectional view illustrating a cross section taken along the line AA in FIG. 4. In these drawings, the antenna cover B1 is formed by superposing two cover members B11 and B12 formed of, for example, a substantially rectangular paper with chamfered squares, non-woven fabric or cellophane, and an edge portion of an oblique one-dot chain line shown in FIG. These cover members B11 and B12 are bonded to each other by an adhesive B13. That is, the edge area bonded with the adhesive B13 is an edge area on the three sides of the cover members B11 and B12. By this bonding, a housing portion B14 for housing the antenna element is formed in the central region between the opposing surfaces of the cover members B11 and B12. The inner shape of the housing portion B14 has substantially the same shape as the outer shape of the antenna element (resin plate A13). Further, as shown in FIG. 5, an adhesive part B15 coated with, for example, an acrylic adhesive is formed on the outer surface of the cover member B12 except for a knob part B17 described later, and the antenna cover B1 is attached to the subject 1.
