The present invention relates to a roofing shingle, which can surely prevent water such as rainwater from leaking through a roof. A roofing shingle has a rectangular plate (11) provided with first through fourth seam portions (11a-11d). The first and second seam portions (11a, 11b) are positioned in a pair along opposite side edges of said plate and folded in opposite directions with respect to a plane of said plate. The third and fourth seam portions (11c, 11d) are positioned in a pair along opposite end edges of said plate and folded in opposite directions with respect to the plane of said plate. The roofing shingle comprises a waterproofing sheet member (20) having a sheet (21) with its configuration greater than that of said plate and adhesive layers (22a, 22b) provided on both sides of the sheet. The sheet member is positioned and adhered on the plate (11) so that a gap or space formed between the seam portion and a corresponding seam portion of an adjacent roofing shingle is closed and filled with an edge portion (21a, 21d) of the sheet.
