る。Effects of the Invention In the present invention, a silver foil forming a part of the loop antenna is provided on the circuit board, and parallel conducting wires are connected to both ends of the silver foil to form the loop antenna. Therefore, the loop antenna can be constructed using a small area of the circuit board. Can be configured. Moreover, since this loop antenna is placed on the substrate on which the receiving circuit is formed, the wiring from the antenna section to the receiving circuit can be handled using the copper foil of the substrate, so there is no need for lead wire wiring. An external antenna terminal can be connected to any intermediate tap of this loop antenna, and disturbances such as spurious noise and images when using an external antenna can be easily reduced, and an inexpensive radio receiver can be provided as a whole.
