PROBLEM TO BE SOLVED: To provide a deep box-shaped molded product not causing the warpage of a corner part or the inward warpage of a side wall part. SOLUTION: The deep box-shaped molded product is equipped with a main thick-walled part 56, which is formed along the plane of the planar part 53 at the corner part 50A between a deep outside vertical wall part 52 and a front part 53, and a sub-thick-walled part 57, which is formed so as to almost linearly extend to the leading end part of the outside vertical wall part 52 from the main thick-walled part 56. The main thick-walled part 56 and the sub-thick-walled part 57 have hollow parts 56A and 57A, which communicate with each other, provided therein. The warpage of the corner part 50A causing the opening of the front part 53 and the outside vertical wall part 52 can effectively be prevented by forming the main thick-walled part 56 to the corner part 50A. Since the sub-thick-walled part 57 is formed to the outside vertical wall part 52, the outside vertical wall part 52 is reinforced and inward warpage, such that the opening leading end of the outside vertical wall part 52 warps to the inside of a toilet washstand 50, can be effectively prevented.
