PROBLEM TO BE SOLVED: To provide a synthetic sleeper for a railway easily obtaining desired durability without further increasing the number of parts. SOLUTION: In synthetic sleeper bodies 11 mainly composed of a synthetic resin material in each sleeper 10... supporting rails 4, 4, two long-sized tabular synthetic resin materials 12 and 12 are configured by superposing and laminating each opposed surface 12a and 12a. IC tags 13 with IC chips 13a with connected antennas 13b are buried into housing recessed sections 12b and 12b recessed-formed to the opposed surfaces 12a and 12a, respectively, among the synthetic resin materials 12 and 12 for the synthetic sleeper bodies 11.
