In a deterioration diagnosis device (101), a calculation unit (105) estimates a performance of an apparatus during actual operation under a same environmental condition as an environmental condition at a testing time based on operation data (201) including a performance value obtained by measuring a performance of an apparatus during the actual operation, and one or more condition value indicating an environmental condition during the actual operation. The calculation unit (105) calculates a correction factor being a ratio between the performance value obtained by estimation, and a performance value obtained by testing a performance of the apparatus before deterioration. The diagnosis unit (107) compares a performance value obtained by testing a performance of the apparatus after deterioration with a product of a performance value included in new operation data (201) and the correction factor so as perform a deterioration diagnosis of the apparatus.
