A distance estimation device includes a mobile terminal transmitting a radio wave and an in-vehicle device. The in-vehicle device includes a direction determination unit having a receiver, a distance measurement unit, and a correction unit. The receiver receives the radio wave and is arranged on a side of the vehicle. The direction determination unit determines a direction from which the radio wave comes based on a signal strength of the received radio wave. The distance measurement unit receives the radio wave and measures a distance from an installation position of the distance measurement unit to the mobile terminal based on information other than a signal strength of the received radio wave. The correction unit corrects the measured distance to be a distance from an edge of the vehicle to the mobile terminal based on the determined direction and the installation position.
