Abstract:
To provide a barrel which can reduce weight and which can reduce a bottom area, while suppressing strength becoming weak and cost becoming high, and to provide a manufacturing method of a barrel.SOLUTION: A barrel includes an upper part 10, a lower part 30, and a trunk part 20 provided between the upper part 10 and the lower part 30. The lower part 30 and the trunk part 20 are integrally constituted. Between the upper part 10 and the trunk part 20, a joint part 40 is provided. A first thickness of a trunk upper end part 21 in the range of a first distance D1 from the joint part 40 is substantially the same as a thickness W0 of the upper part 10.
