A manufacturing method of a pyroelectric material, comprising heating a solution obtained by dissolving fatty acid metal salts in an organic solvent so as to manufacture a pyroelectric material constituted with an oxide containing iron, manganese, bismuth, and lanthanum,

• wherein in the pyroelectric material, a ratio of the number of the manganese atoms to the sum of the number of the iron atoms, the number of the manganese atoms, and the number of titanium atoms is equal to or greater than 1.0 at % and equal to or less than 2.0 at %, and a ratio of the number of the titanium atoms to the sum of the number of the iron atoms, the number of the manganese atoms, and the number of the titanium atoms is equal to or greater than 0 at % and equal to or less than 4.0 at %.
