At this time, the touch sensing unit may include at least one type of touch film formed with a touch pattern, a touch panel type having at least one touch film attached thereto, a touch pattern shape formed directly on one surface of the cover glass, At least one.

Then, a display accommodated in the case is provided (S40).

After the touch sensing unit is interposed between the cover glass and the display, the input transmitting unit may be provided (S50).

The input transmission unit may extend to the inside of the case and may be electrically connected to the touch sensing unit, and may be electrically connected to the outside of the case.

Further, when the case has a protrusion interposed between the touch sensing part and the display, the input transmission part may be bent along one side of the protrusion, or may extend through the protrusion to be electrically connected to the touch sensing part.

At this time, the step of providing the input transfer unit may include the following steps.

First, one end of the input transmission unit is disposed on the outer surface of the case (S52).

Then, the other end of the input transmission unit is connected to the touch sensing unit to be contacted (S54).

The input transmission unit may be bent so as to enclose the inside of the case from the outer surface of the case through the lower end of the case so that the other end of the input transfer unit contacts the touch sensing unit.

As described above, according to the method for manufacturing a portable terminal of the present invention, the design restriction by the protruding key shape can be solved by a relatively simple method, the production process can be simplified, and the productivity can be improved.
