It is an object of the present invention to reduce the water content of treated matter after hydrothermal treatment and thus reduce energy required for separating and removing moisture from the treated matter after the hydrothermal treatment. A hydrothermal treatment device (3) is a hydrothermal treatment device (3) performing hydrothermal treatment by heating high-water-content biomass, the hydrothermal treatment device (3) including a treatment container (21) that stores sludge, a sludge supply unit (22) that supplies the sludge to inside of the treatment container (21) such that a space (S) is formed in a vertical upper part of the treatment container (21), a stirrer (23) that is provided within the treatment container (21) and stirs stored matter such that counter flows in an up/down direction occur, and a heat transfer tube (24) that is disposed in a horizontal direction within the treatment container (21) and heats the sludge with heat of vapor flowing within the heat transfer tube (24).
