摘要： Provided are a concrete tile manufactured according to an extrusion molding method, and a molding material for manufacturing the concrete tile. The concrete tile includes a tile body 2 having a cut end face 1 in at least one side thereof. The cut end face 1 has a rough-surface shape on a cut surface thereof formed during manufacture of the tile. Alkali-resistant fibers comprising at least one member selected from the group consisting of polyvinyl alcohol-based fibers, polyethylene fibers, polypropylene fibers, acrylic fibers, and aramid fibers are dispersed in the entire thickness of the tile body in a state substantially free of a fiber-containing granular body. Flexural strength of a cut piece of 30 mm × 150 mm is not less than 6 N/mm 2 .
