To provide a portable terminal which can detect the using modes of the portable terminal, can reduce the number of members necessary for detecting the using modes and further can reduce leakage magnetic force badly influencing on other devices.A portable terminal 10 includes a first casing 11 and a second casing 12 having inner side surfaces 11a, 12a capable of opposing to each other, respectively, and a hinge 13 for coupling the first casing 11 and the first casing 11. The first casing 11 is provided with magnetic materials 21, 22a, 22b and the casing 12 is provided with magnetic sensors 24, 25a, 25b for detecting the magnetic materials 21, 22a, 22b, respectively. The magnetic sensors 24, 25a, 25b and the magnetic materials 21, 22a, 22b detect the using modes including a folded state or a bent state of the first casing 11 and the casing 12.
