[Object] To provide a portable terminal device that prevents incorrect input by the touch sensor from taking place during sliding and opening of a case. [Constitution] A mobile phone of the present invention includes: a first cabinet 1; a second cabinet 2 that is slidable along an upper surface of the first cabinet 1; a first touch sensor 36 that enables input by touching the upper surface; a projection 23 that projects from the second cabinet 2 toward the upper surface; a second touch sensor 37 that detects a position of contact of the projection 23 with the upper surface; and a CPU 100 that controls input by the first touch sensor 36 in accordance with output from the second touch sensor 37. The CPU 100 enables input by the first touch sensor 36 when the second cabinet 2 is in a first position (OP position) where the second case exposes a detection area of the first touch sensor 36 to the outside, and disables input by the first touch sensor 36 when the second cabinet 2 is out of the first position (OP position).
