A shoe press belt capable of preventing the occurrence and growth of cracks therein and is used in a paper-making press apparatus containing a press roll, a belt, and a pressure shoe for pressing a material web, wherein the shoe press belt includes a reinforcing layer, a first elastic material layer, and a second elastic material layer. A plurality of grooves are formed at an exterior peripheral surface region of the first elastic material layer. The bottom of the grooves at an axial end region of the belt corresponding to at least one of an end-proximate region in an axial direction of the pressure shoe and an end-proximate region in an axial direction of the press roll extends toward the reinforcing layer relative to the bottom of the grooves at a region other than the end region.
