A circular saw with a dust-collecting hood is to provide a circular saw structure with high dust-collecting efficiency, excellent safety and convenience in operation. By designing the dust-collecting hood and its location, the dust-collecting hood has surrounding wings to snugly attach to a main body of the circular saw and to further close two sides of a saw sheet so that small pieces and dust do not disperse and can be conducted into the dust-collecting hood by the air current when sawing. Moreover, an outer current is provided to suck the small pieces and dust out of the dust-collecting hood to significantly improve the dust-collecting efficiency. Because the structure is simple, the circular saw has low manufacturing cost and other advantages such as long lifetime and stable safety.
