A method for manufacturing a discharge surface treatment electrode includes: a first laying of laying powder particles to form a first powder layer; and a first binding of binding some of the powder particles in the first powder layer to each other. The method further includes: a second laying of further laying the powder particles on the first powder layer in which some of the powder particles are bound to each other to form a second powder layer; and a second binding of binding some of the powder particles in the second powder layer to each other to form a stacked body of granulated particles. A region having a different porosity from another region is formed inside the stacked body.
