Abstract
An electronic apparatus has a demodulating section and a strap antenna having a conductor in its inside. Radio waves received by the strap antenna are demodulated by the demodulating section. A receiving-sensitivity adjustment member has at least one through hole for passing the strap antenna in it is slidably placed on the strap antenna, and since a magnetic substance built in the receiving-sensitivity adjustment member changes the electric field generated in the conductor of the strap antenna, receiving sensitivity can be adjusted to the most appropriate state. With an insulator member placed on the strap antenna, a loop antenna can be used as a monopole antenna. When the strap antenna is made detachable, another antenna can be used depending on the use condition.
