Provided is a polishing pad, which alleviates the problem of scratching that occurs when conventional hard (dry) polishing pads are used, exhibits an excellent polishing rate and polishing uniformity, and can also be used for not only primary polishing but also final polishing, and also provided is a manufacturing method therefor. The polishing pad includes a polishing layer that has polyurethane-polyurea resin foam containing generally spherical bubbles, and is characterized in that the hard segment content (HSC) of the polyurethane-polyurea resin foam calculated using formula (1) is in the range of 26-34%, and a density (D) of the polyurethane-polyurea resin foam is in the range of 0.30-0.60 g/cm3. (1): HSC=100×(r-1)×(Mdi+Mda)÷(Mg+r×Mdi+(r-1)×Mda) |
