Leakage of a pressurizing fluid contained in a pressurizing chamber from a sealer is suppressed. In a double-belt press, the sealer that seals the pressurizing chamber includes an inner seal, an outer seal, and a partition wall. The inner seal has an inner seal flow passage having an intake port via which a sealing fluid supplied into an inner sealing groove is taken in and a jet port via which the sealing fluid taken in via the intake port jets toward belts, the intake port and the jet port being formed at opposite ends of the inner seal flow passage. The outer seal has an outer seal flow passage having an intake port via which the sealing fluid supplied into an outer sealing groove is taken in and a jet port via which the sealing fluid taken in via the intake port jets toward the belts, the intake port and the jet port being formed at opposite ends of the outer seal flow passage. The partition wall has a plurality of fluid supply passages that supply each of the inner sealing groove and the outer sealing groove with the sealing fluid and a plurality of fluid recovery passages that recover the sealing fluid accumulating in the space formed between the inner seal and the outer seal, the fluid supply passages and the fluid recovery passages being provided in positions different from one another in a direction along the outer edge of the pressurizing chamber.
