A touch input device includes a touch sensing element having at least two input parts partitioned by at least one partition line, a plurality of force sensors mounted on a bottom surface of the touch sensing element, and at least one support member mounted on the bottom surface of the touch sensing element to provide reaction force to an elastic sensing element in a vertical direction and serving as the partition line. In at least one of the two input parts, a moment based on a shearing force may be canceled by the support member.
