Each of the first side surfaces 105 includes a side flange 105a. A protruding width of the side flange 105a from the first side surface 105 is equal to or less than a protruding width of the second side surface 106 from the first side surface 105. A metal roofing member 1 is arranged on a roof base while abutting at least the second side surface 106 against a second side surface of other metal roofing member.
