PROBLEM TO BE SOLVED: To provide a fitting-in type resin-made tile capable of being simply connected, making it hard to come off easily, laying it in a short time, withstanding traject of a heavy object such as an automobile sufficiently, being simply removed to enable its reuse, and being disposed by burning it up. SOLUTION: This fitting-in type resin-made tile is constituted by forming a contact face of a fitting recessed part for connection and a fitting projecting part for connection into a tapered shape, fixing it firmly, and forming a structure for preventing the fitting projecting part for connection from passing through the fitting recessed part for connection from below to above to obtain enough connection strength for letting it withstand traject of the heavy object on it. Even if polylactic acid resin is mainly used as a material constituting this fitting-in type resin-made tile, a non-vinyl chloride resin-made tile enabling the heavy object to pass through on it and improving possibility of planting plants is obtained.
