Among these, the slide type personal portable terminal refers to a personal portable terminal in which a slide part disposed to overlap each other with the main body part is slidably opened and closed with respect to the main body part. For example, a typical slide-type personal portable terminal includes a main body and a terminal body including a slide portion disposed to overlap the main body portion, and a slide module connecting the main body portion and the slide portion so that the slide portion can be relatively sliding relative to the main body portion. It is composed.

On the other hand, in the conventional slide-type personal portable terminal, the housing forming the appearance of the terminal body is generally formed by injecting plastic. However, in order to maintain a certain shape strength due to the characteristics of the material as the housing is injection molded into plastic, there is a problem in that it is difficult to slim down because there is a limit in reducing the thickness.

In addition, the slide module of the conventional slide-type personal portable terminal has a problem that it is difficult to reduce the thickness more than a predetermined portion is configured to play a role corresponding to each of the main body portion and the slide portion constituting the terminal body different from each other.

That is, in the related art, the slide module is formed separately from the housing forming the exterior of the terminal body, and is configured to be coupled in a double overlapped form, thereby increasing the thickness of the terminal.
