PROBLEM TO BE SOLVED: To provide a digital broadcast receiver which can easily rewrite data. SOLUTION: The digital broadcast receiver comprises a flash memory, an antenna input terminal 1 to input a reception signal from an external antenna, a loop antenna 11 formed of a portion of a printed wiring pattern of a printed wiring board, a down-conversion unit (a local oscillator 3 and a mixer 4) to frequency-convert the reception signal from the external antenna or a reception signal from the loop antenna 11, a field-effect transistor 12 provided between the loop antenna 11 and down-conversion unit, a demodulating circuit 5 to digitally demodulate a signal output from the down-conversion unit, and a control unit (a microcomputer 6 for signal processing and a main microcomputer 9) to rewrite data in the flash memory 7 based upon a signal output from the demodulation circuit 5.
