PROBLEM TO BE SOLVED: To provide a thermostat and an engine cooling device equipped with the thermostat, maintaining cooling water temperature at the proper temperature corresponding to an engine request by improving the thermosensitivity of a temperature sensing part while suppressing increase of a pressure loss when cooling water passes the thermostat. SOLUTION: The thermostat 50 includes a merging passage 59B, an outlet 52A, the temperature sensing part 54 displacing while sensing temperature of the cooling water existing around the temperature sensing part, and a valve element 55 opening and closing based on the displacement of the temperature sensing part 54 to adjust an amount of the cooling water flowing in a radiator. The temperature sensing part 54 lies on the stream line of the cooling water flowing to the outlet 52A from the merging passage 59B irrespectively of its displacement position to be interposed between the merging passage 59B and the outlet 52A, and its axis ST is offset to the left side in a lateral direction W more than the inlet axis SW of an inlet 21 of a water pump connected to the outlet 52A.
