Abstract
The accuracy of a measurement value obtained by a tire pressure detection device is lowered by a centrifugal force and an inertial force during travel. A pressure sensor () displaces a diaphragm () in its vertical direction () according to the pressure. The pressure sensor () is arranged in a tire () with the vertical direction () directed to a direction parallel to a rotation axis () instead of the tire circumferential direction or radial direction. The pressure sensor () is mounted onto a substrate with the vertical direction () of its diaphragm () directed in parallel to the substrate surface and the substrate is bonded to a tread portion of the tire () and a wheel rim portion while adjusting the vertical direction () of the diaphragm () with the direction of the rotation axis ().
