Abstract: PURPOSE: An antenna-built in mobile phone for reducing electronic wave absorption rate is provided to allow a user to stably and reliably carry a mobile phone by mounting an antenna inside the mobile phone and positioning an electronic wave absorbing unit to remove or at least considerably reduce the amount of a harmful electronic wave absorbed to a human body from the mobile phone body and the antenna. CONSTITUTION: An electronic wave absorbing unit(16) is installed between an antenna(17) and an internal circuit(19). The electronic wave absorbing unit(16) absorbs an electronic wave reflected from a conductor plate constituting the circuit board(19), to thereby reduce influence to a resonation of the antenna(17). Thus, the antenna(17) maintains its intrinsic characteristics even inside the mobile phone(10), thereby faithfully playing its role. The electronic wave absorbing unit(16) absorbs even an electronic wave directing to a human body after being generated from a front side of the mobile phone(10). Thus, an amount of electronic wave radiated while the user carries the mobile phone, that is, an SAR(specific absorption rate), can be remarkably reduced.
