Zusammenfassung:	Pressing a protective member causes the protective member to be embedded in boundaries of adjacent ones of a plurality of devices serving as recesses on a front surface side of a substrate, and the protective member is ground so that the front surface side of the protective member is planarized. This makes it possible to eliminate a gap between the substrate and the protective member or to reduce this gap in size, while making it possible to eliminate a gap between a chuck table holding the substrate through the protective member and the protective member or reduce this gap in size. Hence, by carrying out these steps prior to grinding of the back surface side of the substrate, it is possible to prevent the back surface side of the substrate from becoming uneven, in association with grinding of the back surface side of the substrate.
