To attain a reduction of weld working load at the fabrication of boiler water wall panel and attain a reduction of maintenance load and enhancement of rate of operation for a furnace housing with built-in boiler water wall panel. Boiler water wall panel (80) comprises panel body (70) with water channel having constituent units of metallic seamless finned single tubes (60) integrally fabricated by hot extrusion technique, etc., these metallic seamless finned single tubes at the distal end of fin portion (62) welded and connected to each other as seam (71) and, provided on at least one surface side of the panel body (70), internal central region weld coating (82) and periphery weld coating (81) of anticorrosion alloy. The finned tube body (60) has tube body part (61) for cooling water channel and, extending on both sides thereof in the direction of tube body axial line, a pair of fin portions (62) wherein intervening portion (63) has an external surface formed into a concave curved surface of 3 to 6 mm curvature radius.
