[Subject] To provide a mount structure of a touch input device having a pressure sensitive sensor in which visibility can be prevented from being lowered even when the pressure sensitive sensor is mounted, water-proofness and dust-proofness are excellent, and a pressure can be easily detected with high measurement accuracy.
[Solution] According to a mount structure of a touch input device which includes a touch input device 4 having at least a touch panel 10, and a pressure sensitive sensor 20 attached to a lower surface thereof, and a casing 2 dented to allow the device to be externally fitted in, and having a concave part or an opening part for a display device, and a frame-shaped support part 2b to support a back surface peripheral part of the touch input device 4, in its bottom surface, the pressure sensitive sensor 20 includes a pressure concentration member 26 laminated and arranged in a dot shape so as to support the pressure sensitive ink member on a back surface, and a frame-shaped gasket 40 is attached between the pressure sensitive sensor 20 and the support part 2b of the casing 2, in which the gasket 40 does not overlap with the pressure concentration member 26.
