1. A strain inducing body comprising:
a strain inducing portion including a movable portion that deforms in response to force or moment in a predetermined axial direction and a non-movable portion that does not deform in response to the force or moment; and
an input transmitter that is connected to the non-movable portion and does not deform in response to the force or moment,
wherein the input transmitter includes,
a first frame portion,
a plurality of first beam structures each of which has one end thereof connected to the first frame portion and extends from the first frame portion to an inside of the first frame portion,
a first coupling portion that connects other ends of the first beam structures,
an accommodating portion that is provided inside and is fixedly connected to the first coupling portion and that is capable of housing a sensor chip to detect the force or the moment.
