A composite material for piezoelectric transduction which exhibits a sufficient piezoelectricity, can be suitably utilized in various fields as a damping material and the like, and can be suitably utilized in the fields that require heat resistance. The composite material for piezoelectric transduction of the present invention absorbs external vibration or the like as strain energy, efficiently transforms the strain energy into electricity, and is capable of dissipating the electricity as heat, by using a material for piezoelectric transduction which is excellent in mass production at low cost and handlings. One of the preferable aspect of the composite material for piezoelectric transduction is to include a domain which exhibits piezoelectricity in a matrix material of the composite material for piezoelectric transduction, in which the domain is formed of a material for piezoelectric transduction which contains a main chain liquid crystal polymer.
