Multilayer displacement element and method for manufacturing same

摘要

A multilayer displacement element is formed by alternately stacking a plurality of ceramic layers and a multiplicity of internal electrodes, wherein each of the ceramic layers is composed of ceramic grains containing barium titanate as a main component. The ceramic grains preferably have an average diameter equal to or larger than 3.5 mum and it is desirable that the ratio of one grain to one layer for the ceramic layer be equal to or larger than 20%.
