A caliper body of a floating-type disk brake includes a cylinder-part constituent part including a cylinder bore into which a piston pressing brake pads against a disk rotor is disposed, a bridge part extending from the cylinder-part constituent part and including a through-hole, and a claw-part constituent part formed on a leading end side of the bridge part and disposed so as to be opposite to the cylinder-part constituent part. In a method of manufacturing the caliper body of the floating-type disk brake, a mold in which sprues are provided in at least two places spaced apart from each other in a disk rotor circumferential direction on a region corresponding to the claw-part constituent part is prepared. Molten metal is poured from the sprues of the at least two places of the mold, and starts to solidify from a side of the cylinder-part constituent part.
