PURPOSE: An air curtain is provided to prevent ventilation blanket coverage from being generated by minimizing gap between air outlets and uniformly and widely forming the air curtain using a ventilation spreading unit and a ventilation guide part. CONSTITUTION: An air curtain comprises a case, a suction fan, a driving unit, and a ventilation spreading unit. A plurality of outlets are formed at constant intervals in the case(2). Inlets(2a,2b,2c) are formed in the case. The suction fan is built in the case. The suction fan(6) sucks outer air through the inlet of the case and discharges the air to the outlet. The driving unit is built in the case. The driving unit is driven to deliver the outer air, sucked through the inlet, to the suction fan. One end of the ventilation spreading unit(8) is formed on the suction fan. The other end of the ventilation spreading unit is formed on the outlet of the case and induces the air to be ejected and diffused.
