Abstract
A complex according to the present disclosure contains a β-eucryptite crystal phase and a lithium tantalate crystal phase. In a temperature range of 0 to 50° C., a coefficient of thermal expansion calculated for each 1° C. is within 0±1 ppm/K. Calcium is contained in the lithium tantalate crystal phase. The volume ratio of the β-eucryptite crystal phase to the lithium tantalate crystal phase is from 90:10 to 99.5:0.5.
