The slide module according to the present invention having such a configuration is mounted on a mobile communication terminal to enable a sliding operation. The user has an upper member having a screen portion for implementing a screen, based on a lower member provided with a keypad, etc. When pushing upward, the upper member is raised by the operation of the slide member 20 and the base member 10 which constitute the slide module provided therein.

Here, in the present invention, when the slide member 20 is raised, the user pushes while pushing, so that a load acts on the slide member 20, wherein a gap exists between the slide member 20 and the base member 10. The smooth sliding operation is to be made, the base member 10 and the slide member 20 is in contact with the gap is reduced by the load.
