LEAD-FREE PIEZOELECTRIC CERAMIC COMPOSITION AND PIEZOELECTRIC ELEMENT
A lead-free piezoelectric ceramic composition includes a main phase containing an alkali niobate/tantalate perovskite oxide, and a subphase containing a spinel compound containing Ti (titanium). The piezoelectric ceramic composition contains Mn (manganese). A Ti content x is greater than 0 mol % and not greater than 4 mol %, and the Ti content x and an Mn content y satisfy an expression, x2/y≤20.0.
