A powder spray device includes a funnel member, a first three-way joint, an air-current supply tube, a discharge tube, a vibration motor, a bypass air-current tube, and a switching mechanism. The first three-way joint has a first opening connected to an outlet at a lower end of the funnel member. The air-current supply tube and discharge tube are respectively connected to second and third openings of the first three-way joint. The vibration motor is fixed onto an outer surface of a funnel body of the funnel member. The bypass air-current tube branches off from the air-current supply tube and is connected to the discharge tube. The switching mechanism switches from and to standby state, in which compressed gas is sent only through the bypass air-current tube, to and from spray-coating state, in which compressed gas is sent out through the air-current supply tube, and also through the bypass air-current tube.
