An object of the present invention is to mitigate an influence of a physical quantity other than strain of a tire on a measurement result of a strain sensor and to improve measurement accuracy of the strain sensor. A strain amount detection device according to the present invention calculates an estimation value of a load applied to a tire by using data describing a relationship among an actually measured strain amount, a tire air pressure, a vehicle speed, a tire temperature, and a tire load.
