Abstract

See full text

A tubular metal body includes a tubular part having an opening at one end in an axis direction; and a bottom part disposed at another end of the tubular part in the axis direction. The ratio (Rz1/Rz2) of a surface roughness Rz1 of an outer peripheral surface of the bottom part to a surface roughness Rz2 of an outer peripheral surface of a center portion of the tubular part in the axis direction is in a range of 2 or more and 4000 or less. A Vickers hardness HV1 of the outer peripheral surface of the bottom part is 5 HV or more and 27 HV or less smaller than a Vickers hardness HV2 of the outer peripheral surface of the center portion of the tubular part in the axis direction.
