A power supply device with a distributed type is provided to simplify the wring of a circuit board and enhance power use efficiency. An SMPS(Switching Mode Power Supply)(2) supplies power to components of the first group including a front panel(10), a fan(18), a tuner(22) and an AV switching IC(20). A DC/DC converter(3) supplies power to components of the second group which does not belong to the first group. The components of the second group include a decoder(12), a storing device and communication interface(14), and a demodulation IC(16). The components of the first group are closer to the SMPS(2) than the DC/DC converter(3). The components of the second group are closer to the DC/DC converter(3) than the SMPS(2).
