PROBLEM TO BE SOLVED: To solve the problem that, in a mobile phone that can be opened/closed in length and width directions, when a function is packaged for automatically connecting a line when a case is opened in the length direction in call arrival, the line may be erroneously connected with the case is opened in the width direction in call arrival. SOLUTION: A folding portable terminal device wherein a first case 1 and a second case 2 are connected via a hinge part 3, includes: a first turning shaft 9 for opening/closing the hinge part 3 in a length direction with respect to the first case 1; a second turning shaft 10 for opening/closing the second case 2 in a width direction with respect to the hinge part 3; length-direction opening/closing detecting means for detecting an open/closed state between the first case 1 and the hinge part 3; and width-direction opening/closing detecting means for detecting an open/closed state between the hinge part 3 and the second case 2. When the hinge part 3 is opened/closed in the length direction, the length-direction opening/closing detecting means detects opening/closing and when the second case 2 is opened/closed in the width direction, the width-direction opening/closing detecting means detects opening/closing, thereby avoiding erroneous detection.
