To provide a working table with air curtain, excellent in workability and shieldability without concern about drying of a specimen or the like placed on the working table by airflow composing an air curtain and without damaging the function of the air curtain by disturbance of the air flow due to a worker' arm or the like.

A push-side chamber 5 and a pull-side chamber 6 are provided at both sides of a longitudinal direction of a table top 4A, respectively. Airflow is blasted out from the blowoff port of the push-side chamber 5 toward the suction port of the pull-side chamber 6 and thereby, the air flow generates a horizontal air curtain above the table top 4A. Air is sucked from the fine air holes h dispersed on nearly the whole surface of the table top 4A, and drying of a specimen or the like placed on the table top 4A by airflow of the air curtain is avoided. Thus, leakage or diffusion of harmful substances into the room is prevented.
