摘要： Provided is a transportation roller, a transportation unit, a printing apparatus, and a method of manufacturing a transportation roller capable of reducing warpage with the elapsing of time. A transportation roller includes: a roller body which is formed in a cylindrical shape by subjecting a metal sheet to a pressing process and allowing a pair of end portions thereof to face each other, and has a joint formed between the pair of end portions, wherein in a sectional shape perpendicular to the axis of the roller body, a thickness of a joint facing portion facing the joint with the axis interposed therebetween is larger than a thickness of a joint portion provided with the joint, and a thickness of the roller body connecting the joint facing portion and the joint portion is gradually changed as it goes from the joint facing portion to the joint portion.
