PURPOSE: To obtain a wristwatch type radio receiver of a simple structure which has facilitated wiring work, by storing each function circuit part of a radio set within an approximately circular and unified case.

CONSTITUTION: A receiver case 5 has an approximately circular and unified form in which a bar antenna storing part 1, a speaker storing part 2, a control panel part 3 and a battery storing part 4 are set adjacently to each other to store each function parts and function circuit. The case 5 consists of an approximately circular base 6 and an approximately U-shaped cover 7 and an opening/closing cover 8 for storage of battery which are provided along the outside of the base 6. A pair of flexible belts 9 and 10 are set at both end parts of the case 5. Thus the radio receiver can be put on a wrist by means of a hooking metallic parts 11.
