1. A light emitting structure configured to emit light in response to a load applied to an object from a load object, wherein:
the light emitting structure
is disposed on a support surface of the object, and
includes a contact portion that is formed to have a predetermined length from a surface of the support surface in a direction perpendicular to a surface of the object;
the contact portion contains a mechanoluminescent material on at least a part of a surface thereof;
a light emitting layer containing the mechanoluminescent material is disposed on a surface thereof;
a material layer is disposed on the light emitting layer; and
the material layer has a Young's modulus larger than that of the light emitting layer.
