An obtaining device provided in a tire cavity region for obtaining tire information related to a condition of a tire includes: a sensor that detects the state of gas in the tire cavity region as the tire information; a valve; and a housing having an internal space for containing the sensor in a state of being compartmentalized from the tire cavity region, a ventilation hole for allowing communication between the internal space and the tire cavity region, and a communication hole connected to a cavity region side opening part of the valve at an end portion on the tire cavity region side and allowing communication between the cavity region side opening part and the tire cavity region. The diameter of the communication hole and the inner diameter of the valve have a minimum value of not less than 2.5 mm, and the ventilation hole is provided at a position outside a range of less than 140 of the angle of view from a center position corresponding to the position of the opening of the communication hole with respect to a central direction aligned with the direction of extension of the communication hole from the opening of the communication hole at the end portion on the tire cavity region side.
