A manufacturing method of a fibrous perovskite-type oxide catalyst includes: a first preparing step; a jetting step; a heating step; and an impregnating step. The first preparing step prepares a first solution by mixing metal salts containing La, Sr, Fe, Co and O elements, a first polymer, a metal salt containing a Zn element and a first solvent. The jetting step jets the first solution by using an electrospinning method to produce a precursor fiber. The heating step heats the precursor fiber to produce a perovskite-type oxide mixed with a Zn oxide. The impregnating step impregnates the perovskite-type oxide with an alkaline solution to remove the Zn oxide.
