To provide a tire information acquisition device which can minimize a weight of a sensor unit and inhibit influence on a weight balance of a tire.SOLUTION: A tire information acquisition device includes: a sensor unit 20 attached to a tire inner surface 2 and including a sensor 21 for acquiring tire information; and a power supply unit 30 attached to a wheel 3. The power supply unit 30 has an electric power supply mechanism 31 which supplies electric power to the sensor unit 20 in a non-contact manner. The sensor unit 20 has: an electric power receiving mechanism 22 which receives electric power from the power supply unit 30 in a non-contact manner; and an information transmission part 23 which wirelessly transmits the acquired tire information.SELECTED DRAWING: Figure 1
