Abstract: A light emitting structure emits light in response to a load applied to an object from a load object. In the light emitting structure are formed contacting portions which are provided on a supporting surface of the object, and which have a predetermined length from the surface of the supporting surface in a direction perpendicular to the surface of the object, wherein a stress-luminescent material is included in at least a portion of the supporting surface and the surface of the contacting portions.
