In a holder for holding a rolled recording medium, each of a pair of side wall members is opposed to a side end face of the rolled recording medium to regulate a position of the rolled recording medium in a widthwise direction thereof. At least one of the side wall members includes a first section adapted to be brought into contact with the side end face, and a second section adapted to avoid contact with the side end face. A position of the second section is determined such that an upper part of the side end face is free from contact with the at least one of the side wall members, and a position of the first section is determined such that a lower part of the side end face is brought into contact with the first section.
