A strain inducing body includes a strain inducing portion. The strain inducing portion includes a movable portion configured to receive a force in a predetermined axial direction or a moment about the predetermined axial direction and to deform in accordance with the received force or moment. The strain inducing portion includes a non-movable portion configured to receive the force or moment and to not deform in accordance with the received force or moment. The strain inducing body includes an input transmitter coupled to the non-movable portion and including an accommodating portion for accommodating a sensor chip detects the force or moment. The input transmitter receives the force or moment and to not deform in accordance with the received force or moment. The input transmitter transmits deformation of the strain inducing portion to the sensor chip.
