　Provided are a blow molding mold, a blow molding method, and a method for manufacturing a molded article that enable the thickness of a deep drawn portion to be sufficiently maintained when blow molding a molded article in which the deep drawn portion is arranged adjacent to the weld portion of a parison.　The blow molding mold and blow molding method form a molded article having: a weld portion formed by welding the inner surface of the parison; and a deep drawn portion arranged in the proximity of the weld portion. The blow molding mold is provided with a first mold and a second mold that form the weld portion by clamping. The second mold is configured from: a first split mold having a mold surface for forming the weld portion and a mold surface that constitutes a part of a deep draw recess for forming the deep drawn portion; and a second split mold having a mold surface that constitutes the remaining section of the deep draw recess. After blow molding, the deep drawn portion is cut at the mid point in the depth direction to form an opening, and the molded article is completed.
