The present invention provides a casting mold which is capable of preventing damage to the edges of protrusions thereof due to deformation and impact and which comprises: a long side; a short side having both ends provided with protrusions formed inwards; and coating layers formed on the inner surfaces of the long and short sides, wherein each protrusion has a second coating layer formed on at least a part of the edge thereof, and a first coating layer, which has higher hardness than that of the second coating layer, formed on other regions except the part of the edge. |
