A caulking die according to an embodiment of the present invention includes an end surface being connected to each of an upper surface and a lower surface. The end surface includes a first protruded part including a first top portion, a recessed groove, and a second protruded part including a second top portion in sequential order from the lower surface side toward the upper surface side. A length of the second top portion is larger than a length of the first top portion, and a height of the second protruded part is larger than a height of the first protruded part in a cross-sectional view perpendicular to a width direction of the end surface. A caulking tool includes the caulking die. A method for manufacturing a caulking joint uses the caulking tool.
