PROBLEM TO BE SOLVED: To provide a luminescent stick (luminescent element) to be used for an emergency light, an display light source, a luminescent toy, etc. for which a power supply, fuel and chemical illuminant are not used. SOLUTION: A luminescent rod 10 obtained by forming a mechanical stress luminescent material allowed to light when pressurized on the surface and inside of a flexible and elastic rod (stick, long member), and preferably a mechanical stress luminescent stick 100 (mechanical stress luminescent element, mechanical stress luminescent rod) constituted of fixing weights 20A, 20B on the end part of the luminescent rod 10 are provided. It is also available for instance that the end parts of the luminescent rod 10 are expanded to form spherical weights, the whole luminescent stick is made of rubber so as to be handled also by children in an extremely safe state and at easy, both the weights 20A, 20B and the luminescent rod 10 are made of a transparent or translucent material and powder of a mechanical stress luminescent material is charged into the insides of both the weights 20A, 20B and the luminescent rod 10 to illuminate the weights 20A, 20B also, and the rod is formed like a U-shaped rod or like a tuning fork. The luminescent rod 10 and the mechanical stress luminescent stick 100 can be repeatedly allowed to light only by extremely simple operation for griping the one end part of the luminescent rod 10 or the mechanical stress luminescent stick 100 with a hand H and shaking S, swinging or rotating R it.
