A mobile radio apparatus wherein the degradation of communication performance caused by electromagnetic noise can be precluded with enhanced reliability. This mobile telephone unit (100) comprises a camera body (107); a circuit board (106) that includes partial board parts (104, 105) located on the two respective sides of the camera body (107); a camera shield (108) that is located close to and opposed to the back surface of the camera body (107) (which is opposite to the image pickup plane); a camera connection connector (110) that is connected to the camera body (107) and grounded in the partial board part (104); a frequency limiting part (111) that is connected to the camera shield (108) and grounded in the partial board part (105); a feeding part (117) that is located in the partial board part (105); and a matching circuit part (113) that is located and grounded in the partial board part (105). This can limit those ones of the frequencies of interference components dissipated from the camera body (107) to the circuit board (106) which adversely affect the communication, so that the degradation of communication performance caused by electromagnetic noise can be precluded with enhanced reliability.
