Provided is a method for producing a highly active electrocatalyst that can be obtained using a material that is relatively inexpensive and has a relatively large amount of resources, and that can be used in an acidic electrolyte even at a high potential. . A precursor of an electrocatalyst obtained by continuously hydrothermally reacting a mixture containing the following first material and the following second material in the presence of water in a supercritical state or a subcritical state, A method for producing an electrocatalyst including a step of firing under the condition that the following second material is changed to a carbon material: The first material is one or more metal elements selected from the group consisting of Group 4A elements and Group 5A elements, and one or more selected from the group consisting of hydrogen, nitrogen, chlorine, carbon, boron, sulfur and oxygen A non-metallic element composed of a metal compound, The second material is a carbon material precursor.
