A casting method and apparatus using a resin core wherein a portion of a wall of the resin core that receives a greater heat and/or load than other portions of the wall of the resin core, is increased in thickness. As a result, even if the resin core receives more heat and/or load in places, a local deformation or breakage of the resin core is effectively prevented.
