The purpose of the present invention to provide a method for manufacturing a knuckle 50 capable of ensuring favorable castability with which the knuckle 50 capable of suppressing transmission of vibration from a front wheel 4 to a vehicle body is casted and, at the same time, production efficiency is improved, and to provide the knuckle 50. Provided is the method for manufacturing the knuckle 50 that includes a bearing mounting portion 51 on which a hub bearing 40 is mounted, a damper holding portion 541 which holds a damper 20, and a damper mounting arm portion 542 which couples the bearing mounting portion 51 and the damper holding portion 541, the method being such that by using one core 130 the knuckle 50 is integrally casted so as to formed therein a cylindrical opening S1 which is the inner space of the damper holding portion 541, a hollow opening S2 in which the inner space in a hollow portion 544 of the damper mounting arm portion 542, the hollow portion 544 extending in a closed cross section from the damper holding portion 541, is continuous with an opening formed in the damper holding portion 541, and an arm-portion opening S3 which is surrounded by a front arm portion 545 and a rear arm portion 546 of the damper mounting arm portion 542, extending from the hollow portion 544.
