The first hinge portion is locked by being engaged with the first hinge shaft 31. A magnetic flux generator 451M is fixed inside the bearing body 451, a magnetic flux generator 452M is fixed inside the first sliding body 452, and a magnetic flux generator 453M is fixed inside the base 453. The magnetic flux generator 451M, the magnetic flux generator 452M, and the magnetic flux generator 453M are, for example, electromagnets that are formed by winding a coil around an iron core, and extend in this order in the direction from negative to positive in the X4 axis. They are aligned on a straight line, and no magnetic flux is generated in the state shown in FIG.

Here, in the open state of the mobile phone 100 shown in FIG. 13, the first housing 1 is slid in the positive direction of the Y2 axis along the upper side surface 2a of the second housing from the closed state of the mobile phone 100 shown in FIG. It is the state made to do. In the foldable mobile phone 100, the display screen 12a is exposed in both the closed state (see FIG. 1) which is a standby state and the open state (see FIG. 13) which is a use state. Therefore, even in the closed state, it is possible to display the time and mail reception notification on the display screen 12a, and the sub display screen is not required, thereby reducing the cost.
