A sliding-type hand phone which can be adhered closely to the face is provided to minimize the distance between the ear and mouth of a user and the hand phone. The shape of a hand phone is square when it is closed and the slid contact surface of the hand phone is designs in the type of a curved line. Because the sliding trace has a curved structure parallel to the contact surface, the upper part and lower part of the hand phone naturally comes inward in comparison with the middle part when the hand phone is opened.
