The present disclosure illustrates a compressed air tool having a silencer structure. A silencing element and an outer cover are disposed in an air exhaust channel of a main body of the compressed air tool. The silencing element has two walls and a channel. The two walls both have long slits, the long slits of the two walls are misaligned and not directly faced with each other. After the exhaust is inputted via the long slits of one of the two walls, the exhaust is flowed through the channel and emitted to the outside via the long slits of other of the two walls. Therefore, the air flow of the exhaust can be weakened, and the exhaust is then entered the countersink of the outer cover and emitted from the side hole, whereby the effect of silencing and reducing the noise caused by the emitted exhaust can be achieved.
