<p>A mobile terminal includes an upper casing having at least one exposure opening formed by penetrating a predetermined area thereof, a lower casing coupled to the upper casing to face each other and having an accommodation space formed therein and capable of accommodating an internal part assembly including a printed circuit board, and a middle frame arranged between the upper casing and the lower casing and coupled to the upper casing and the lower casing, and supporting installation parts electrically connected to the internal part assembly and installed such that at least part thereof is exposed to the outside through the exposure opening. A resin mold waterproof ring which is injection molded of synthetic resin having elasticity to have a predetermined width along at least part of an edge portion of the middle frame is integrally coupled to the middle frame and, when the upper casing, the lower casing, and the middle frame are coupled one another, the resin mold waterproof ring is pressed by the upper casing and the lower casing to seal a gap between the upper casing and the lower casing.</p> |
