Provided are a press-molding mold, in which cracks and wrinkles to be formed at the corner portions of a press-molded article are reduced regardless of the depth of the drawing, and a press-molding method using that mold. The press-molding mold (1) comprises a die (2) having a recess (2b) and a wrinkle holding face (2a) formed around the recess (2b), a punch (3) having a protrusion (3a) matching the recess (2b), and a blank holder (4) having a cushion face (4a) matching the wrinkle holding face (2a). In the press-molding mold (1), the wrinkle holding face (2a) and the cushion face (4a) form a clamping portion (14), by which a material member (5) is clamped for the press-molding operation. The clamping portion (14) of the press-molding mold (1) is divided by an opening portion (15) communicating with a corner recess (2c) of the recess (2b), into a first clamping portion (14a) and a second clamping portion (14b), by which the material member (5) is clamped.
