ことを特徴とする携帯形情報機器。 In a portable information device having a structure in which an expansion board for expansion is built into the device, an expansion board having a conductive fixing member that allows an external connection connector mounted on the expansion board to pass through and achieves complete conduction through surface contact. When the unit is mounted inside the device, the front surface of the device subjected to conductive treatment and the conductive fixing member fixed to the expansion board contact at the outer periphery,
Furthermore, the portable information device is characterized in that the front surface of the device is covered with a lid that has been subjected to conductive treatment, and the outer periphery is in contact with the front surface of the device that has been subjected to conductive treatment, thereby ensuring reliable electromagnetic shielding.
