A heat exchanger of a high heat exchange efficiency with a small size for its large heat exchanger duty is provided. The heat exchanger comprises: a first compartment 310 for flowing a first fluid A; a second compartment 320 for flowing a second fluid B; a first flow passage 251 passing through the compartment and for flowing the third fluid for exchanging heat with the first fluid A; and a second flow passage 252 passing through the compartment and for flowing the third fluid for exchanging heat with the first fluid B; the first and second flow passages 251, 252 are formed as an integral passage; the third fluid flows through from the first flow passage 251 to the second flow passage 252; the third fluid evaporates in the first flow passage 251 at a specific pressure; the third fluid condenses in the second flow passage 252 at the approximately specific pressure. Since the third fluid flows from the first flow passage to the second flow passage, heat transfer from the first compartment to the second compartment is allowed. High heat transfer coefficient is achieved due to evaporating heat transfer or condensing heat transfer.
