PROBLEM TO BE SOLVED: To provide a cooler capable of suppressing a decrease in cooling performance.SOLUTION: A cooler 1 comprises a fin 20 including a refrigerant inflow port 110a and a nozzle 10 which discharges a supplied refrigerant toward the refrigerant inflow port 110a. The nozzle 10 comprises: a flow passage wall 13 which forms a flow passage of the supplied refrigerant; a nozzle tip 14 which forms a refrigerant supply hole 12 through which the refrigerant flowing in the flow passage is discharged; a pressure receiving part 16 which is provided between the flow passage wall 13 and the refrigerant supply hole 12 and receives force in a discharge direction of the refrigerant; and a thin wall part 15 which is provided between the flow passage wall 13 and the pressure receiving part 16 or in the pressure receiving part 16 and displaces the refrigerant supply hole 12 in the discharge direction of the refrigerant according to the force in the discharge direction of the refrigerant received by the pressure receiving part 16. |
