Abstract: An object is to provide a multifunctional multi-piezo material having both high piezoelectric properties and high mechanoluminescence properties. It is a multi functional multi-piezo material represented by the chemical formula Li(1−X)(1+a)NaXNbO3:MY (where M is at least one type of metal ion selected from transition metal ions), wherein the value of X is in the range from 0.10 or more to 0.98 or less, the value of Y is in the range from 0.0001 or more to 0.2 or less; and α is in the range from 0 or more. Such a multifunctional multi-piezo material has both high piezoelectric properties and high mechanoluminescence properties.
