That is, the thread section is formed such that the thread section 13 should serve effectively in the mouth section such that an interval between a start position and an end position should be 2.0 to 2.5. In the bottle can member 11 which has such a thread section, an outer diameter of the thread section which is formed on the mouth section is 28 to 38 mm.
