PROBLEM TO BE SOLVED: To provide a pyroelectric having both of a high level of insulation and a high quantity of residual polarization.SOLUTION: A pyroelectric of the present invention comprises oxides including iron, manganese, bismuth and lanthanum. The rate of the number of atoms of the manganese to the sum total of the number of atoms of the iron, the number of atoms of the manganese, and the number of atoms of titanium is 1.0-2.0 atom%. The rate of the number of the titanium atoms to the sum total of the number of the iron atoms, the number of the manganese atoms, and the number of the titanium atoms is 0-4.0 atom%.SELECTED DRAWING: None
