摘要： PROBLEM TO BE SOLVED: To provide a portable telephone that can reduce an electromagnetic energy emitted from the inside of the portable telephone to a head of a human body. SOLUTION: The portable telephone 102 has a transmitter 6 that generates a 1st voice signal, a transmission circuit that transmits a 1st radio signal resulting from modulating the 1st voice signal via an antenna 1, a reception circuit that demodulates a 2nd radio signal received by the antenna 1 to generate a 2nd voice signal, a receiver 9 that sounds the 2nd voice signal, a printed circuit board 5 on which the reception circuit and the transmission circuit are mounted, a shield case 4A that suppresses electromagnetic wave interference between the printed circuit board 5 and the antenna 1 and the surface of which is conductive, and a radio wave absorbing body 31 that is closely adhered to an area 49 of the surface of the shield case 4A placed toward a body head 91 in the case of a speech by a conductive adhesive 22.

摘要： PROBLEM TO BE SOLVED: To effectively decrease the local average SAR value in a use state. SOLUTION: A magnetic loss material 12 is joined in a contact state through a conductive adhesive bonding material 11 with the surfaces of the parts, where the human-body absorbed electromagnetic wave quantity at least per unit mass becomes maximum, of a ground conductor 9, a shield case 10, etc., of a circuit board 3 which sends an electromagnetic wave as the surface current excited by an antenna 7 in the used state flows.

摘要： PROBLEM TO BE SOLVED: To effectively reduce a local average SAR(Specific Absorption Rate) in an operating state. SOLUTION: A nonconductive case 11 is provided with communication control sections 23, 26 or the like that are shielded by a shield body such as a ground conductor 14 and a conductive case 15 and with output devices 18, 21 that reproduce outputs from the communication control sections. A magnetic loss material layer section 22 is provided to a mount face of the shield body on which at least the output devices are mounted.
