PROBLEM TO BE SOLVED: To improve cooling performance by increasing q cold air suction amount from a fan duct window hole facing to the direction different from the direction of an inflow port of a cooler. SOLUTION: This open showcase comprises a storage chamber having a side portion opened at least in two directions, a fan duct 3b' having a cold air supply opening 3b<SB>1</SB>at an upper portion of the side portion, a cold air suction opening 3b<SB>2</SB>at a lower portion, and a window hole 3b<SB>3</SB>communicating with the cold air suction opening, and communicating with the cold air supply opening, a fan for sucking the cold air to the fan duct through the window hole, and the cooler 5 disposed in the fan duct in adjacent to the window hole. An air curtain flowing from the cold air supply opening to the cold air suction opening is formed, the fan duct has the window holes directing to each opening direction of the side portion of the storage chamber in a state that the window holes are partially directed in the direction same as the direction of the inflow port of the cooler and the remaining window holes are directed in the direction different from the direction of the inflow port of the cooler, and a guide member 6 for directing the cold air sucked from the remaining window holes to the fan duct to the inflow port of the cooler is disposed in the fan duct.
