A cold spray device basically include at least a pedestal, a base plate, a motor, a spray gun, a high-pressure pipe and a rotating joint. The pedestal is configured to support a workpiece in a predetermined orientation. The base plate is disposed in a position away from the workpiece. The motor is arranged to cause the base plate to rotate about a rotational axis. The spray gun is mounted on the base plate so that a spray direction is directed toward the rotational axis. The high-pressure pipe guides a working gas to the spray gun. The rotating joint is provided to a base end of the high-pressure pipe. The high-pressure pipe is arranged along the rotational axis.
