Reference numeral 4 denotes a holding plate made of a circular insulator. Holding plate 4
Is separated from the housing 3. On one surface, a circular loop antenna 21a is formed near the outer periphery, and semicircular electrodes A and B are formed inside the loop antenna 21a. . The loop antenna 21a and the electrodes A and B are formed by attaching a metal foil such as a copper foil on the holding plate 4 or by etching.
