A method for forming a mold comprises forming a body by kneading a ceramic powder comprising a silicon nitride powder and a first binder solution; forming a slurry by adding a second binder solution to the body; and forming a release layer by attaching the slurry to a surface of a mold base. A method for manufacturing a solar cell element comprises forming a silicon ingot by solidifying a silicon melt in the mold obtained by the above-described method for forming a mold; slicing the silicon ingot into substrates each having a predetermined thickness; forming a diffusion layer on each of the substrates; and forming an electrode on a surface of the diffusion layer.
