<P>PROBLEM TO BE SOLVED: To provide a mobile radio communication terminal capable of suppressing the deterioration of communication sensitivity. <P>SOLUTION: A circuit board 21 on an operation unit side includes a feed unit of a communication antenna 22. A flexible connection board 51 is disposed between the circuit board 21 on the operation unit side and a radiation element 22e of the communication antenna 22, and has a sheet metal 6 in a prescribed shape having one end electrically connected to a ground conductor of the circuit board 21 on the operation unit side and the other end to be an open end. The sheet metal 6 includes: a standing portion 61 to make upright on the circuit board 21 on the operation unit side; a parallel portion 63 on the antenna side, disposed in parallel to the circuit board 21 on the operation unit side and extending from the standing portion 61; and a parallel portion 64 on the board side extending from the parallel portion 63 on the antenna side through a folding portion 62. The parallel portion 63 on the antenna side and the parallel portion 64 on the board side are disposed to be parallel in the thickness direction of the circuit board 21 on the operation unit side, and is disposed between the radiation element 22e of the communication antenna 22 and the flexible connection board 51. <P>COPYRIGHT: (C)2012,JPO&INPIT |
