Abstract
Provided is a dielectric body having a high dielectric constant and a change rate of the dielectric constant of 30% or less, in a temperature range from −50° C. to 350° C. An inorganic substance contains an oxide crystal including A and M (the A being one or more of P, Ge, and V, and the M being one or more of Nb and Ta), in which the dielectric constant is 500 or more. In the inorganic substance, the oxide crystal is one or more of PNbO, PNbO, GeNbO, GeNbO, GeNbO, VNbO, VNbO, PTaO, GeTaO, VTaO, and solid solutions thereof.
