Abstract: PROBLEM TO BE SOLVED: To obtain a spherical pigment based on an oxide or silicate salt carrier material having a finely dispersed metal, and to provide a method for producing the same. SOLUTION: This pigment is obtained by a spray-pyrolyzing method comprising pyrolyzing an aerosol comprising the solution of at least one kind of a noble metal compound and an oxide or silicate salt-forming precursor at a temperature exceeding the decomposition temperature of the noble metal compound and a temperature for forming at least a carrier material from the oxide or silicate salt-forming precursor and subsequently separating the produced pigment from the pyrolyzed gas. The obtained pigment consists mainly of the spherical particles based on the oxide or silicate salt carrier material and the noble metal finely dispersed on or in the particles and having an average particle diameter of
