PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device capable of suppressing reduction in recovery heat quantity along with passage of time. SOLUTION: The exhaust heat recovery device includes: a heating medium circulation passage 2 circulating a heating medium C via an exhaust heat generating device G, a heat recovery part R and an atmosphere opening type heating medium storage tank 1; and a heating medium circulation means 3 circulating the heating medium C through the heating medium circulation passage 2 to recover exhaust heat generated in the exhaust heat generating device G by the heat recovery part R via the heating medium C. The heating medium C includes water W and a freezing-point depressant for depressing the freezing point of the heating medium C. The exhaust heat recovery device further includes: a heating medium supply state control means A controlling the supply state of the heating medium C supplied to the heat recovery part R; a recovery heat quantity measuring means M measuring recovery heat quantity recovered from the heating medium C by the heat recovery part R; and a control means 7 controlling the operation of the heating medium supply state control means A so that the recovery heat quantity becomes target heat quantity based on the measurement information by the recovery heat quantity measuring means M.
