A folding-type mobile terminal comprises: a first body having a first printed-board module inside thereof and having an input unit on a surface of the first body; a second body having a second printed-board module inside thereof and having a display unit on a surface of the second body; a hinge coupling the first body and the second body so that the folding-type mobile terminal is capable of being folded, the hinge being made of a metal; a first metal chassis incorporated into the first body, the first metal chassis extending from the hinge; and a second metal chassis incorporated into the second body, the second metal chassis extending from the hinge. Each of the first body and the second body has the printed-board module, an upper case-member and a lower case-member each fixed to the metal chassis so that the upper case-member and the lower case-member together cover the metal chassis. The upper case-member and the lower case-member are made of a synthetic resin.
