A monopole antenna arranged in an inside of a first case of a portable radio apparatus includes an elementon the power feed side, an elementon the open end side, and a resonance circuit. A width of the elementon the open end side, which comes close to an electronic partsarranged in an inside of a second case and containing a metal in a folded mode, is set smaller than a width of the elementon the power feed side, which does not come close to the electronic parts
