PROBLEM TO BE SOLVED: To provide a spray booth capable of preventing a coating agent from scattering in a room owing to spraying, usable for a long duration with no need of replacement of a filter since no filter is used and without occurrence of clogging of a flow route, and excellent in safety. SOLUTION: A flow route 6 is installed between a suction port 4 and a discharge fan 52. The flow route 6 is formed just like a labyrinth. Projections 62 with a height not so high to close the flow route 6 are formed reciprocally in both sides of inner wall face of the flow route 6. An adsorbent 7 made of a porous substance or the like is formed in the inner wall face of the flow route 6. A plurality of pleat-like projections 62 of the adsorbent 7 are formed in the inner wall face of the flow route 6. COPYRIGHT: (C)2003,JPO
