PROBLEM TO BE SOLVED: To provide a sheet-like elongation organic substrate which has a stress light-emitting region and in which the whole substrate can be easily elongated.SOLUTION: In a sheet-like elongation organic substrate, a stress light-emitting part including a stress emitter and a resin material is partially and integrally formed in an elongation polymer matrix, and a surface shape of the stress light-emitting part or a projection shape when a sheet-like elongation organic substrate surface is assumed to be a projection plane is a solid shape, a linear shape or a ring belt shape. The stress light-emitting part including the stress emitter and the resin material may be partially and integrally formed in a state being exposed to at least one surface of the sheet-like elongation organic substrate or in a state not being exposed, in the elongation polymer matrix. |
