To improve abrasion resistance of a concrete block for a revetment by arranging a resin protective part reacting/hardening even in the presence of moisture in a part or the whole of a surface of a concrete main body.

Resin is injected by a prescribed thickness into a concrete block mold, and concrete is poured into from above it to manufacture a concrete block 1 for a revetment for forming a protective part 3 on a surface of a concrete main body 1. The resin used for the protective part 3 hardens even if moisture exists at hardening time, and for example, a polysulfide modified resin is suitable. The polysulfide modified resin is excellent in an adhesive property and chemical resistance, and is also excellent in flexibility and impact resistance, and exhibits strong adhesive strength to a wetting surface. A surface of the concrete main body 2 is covered with the protective part 3 to improve impact resistance and abrasion resistance of the concrete block 1 for a revetment.
