PROBLEM TO BE SOLVED: To provide a washing solution excellent in the substitution properties with ink for forming a conductor pattern and capable of suitably eliminating the contamination in the flow channel of the ink for forming the conductor pattern of a liquid droplet discharge device and the clogging of a liquid droplet discharge head, and the liquid droplet discharge device using the washing solution. SOLUTION: The washing solution is used for forming the conductor pattern due to an ink jet system and washing the liquid droplet discharge device for discharging the ink for forming the conductor pattern wherein metal particles are dispersed in an aqueous dispersing medium and contains the aqueous dispersing medium, a sugar alcohol B and a surfactant A. The washing solution preferably contains the same kind one as the sugar alcohol B contained in the ink for forming the conductor pattern. The surfactant A contained in the washing solution preferably contains at least a part of a component which constitutes the surfactant B contained in the ink for forming the conductor pattern.
