PROBLEM TO BE SOLVED: To provide a cooler with a defroster improving defrosting efficiency by efficiently supplying heat of a glass tube heater to the cooler. SOLUTION: Cooling fins 23 are provided with cutouts 25, and only the vertical peripheral edges of the cutouts 25 are provided with bent parts 30. The glass tube heater 24 is inserted into the cutouts 25, and the bent parts 30 are brought into contact with a glass tube 27. The cooler can thereby be defrosted by radiating the heat of the glass tube heater 24 from the upper surface of the glass tube 27 and conducting heat from the side surface of the glass tube 27 to the cooling fins 23, thus improving defrosting efficiency.
