Abstract
A mobile terminal device includes: a receiving antenna that repeatedly receives a radio signal including predetermined identification information; a sensor that detects an orientation of the mobile terminal device every time the radio signal is received by the receiving antenna; and a controller that estimates an arrival direction of the radio signal based on radio field intensity of the radio signal which is received by the receiving antenna for each orientation when a plurality of different orientations are detected by the sensor.
