PROBLEM TO BE SOLVED: To provide a tire generated force detection sensor having improved tire generated force detection performance in a fine transient region, and a tire with the built-in tire generated force detection sensor. SOLUTION: In this sensor equipped with a pair of conductive members 16, 17, the conductive member 17 is displaced corresponding to a tire generated force F, and thereby a contact area S between the conductive members 16, 17 can be changed. The contact area S and an electric resistance R between the conductive members 16, 17 are adjusted to be in reverse proportion to each other, and thereby a nonlinear output characteristic (output voltage) can be acquired to an input load (tire generated force), and a great change of the output voltage can be acquired to a change of the tire generated force in the fine transient region. Consequently, the tire generated force detection performance in the fine transient region can be improved. COPYRIGHT: (C)2008,JPO&INPIT
