PROBLEM TO BE SOLVED: To provide an open showcase for reliably eliminating a cold isle generated at the lower portion in the front of a showcase body. SOLUTION: Chill leaked to the lower portion of the front from the front opening of the showcase body 10 is sucked into a third air path 40, thus eliminating the cold isle C generated at the lower portion in the front of the showcase body 10. In this case, first to third threefold air curtains A1, A2, A3, where temperature becomes lower gradually from the outside to the inside, are formed, thus reducing the temperature difference between the second and third air curtains A2, A3. Especially, the third air curtain A3 is formed by discharging chill leaked to the lower portion in the front of the showcase body 10 from the third air path 40, thus lowering the temperature of the third air curtain A3.
