<P>PROBLEM TO BE SOLVED: To provide a light control glass device capable of stopping application of voltage to a light control glass when the light control glass is broken. Ž<P>SOLUTION: This light control glass device 10 includes: an inverter 12 for converting a direct current voltage output from a battery 30 mounted on a vehicle to an alternating current voltage; a light control glass 14 having a light control film 28, of which transmittance changes with application of an alternating current voltage converted by the inverter 12; and conductive parts 16 and 18 connecting the battery 30 and the inverter 12 to each other. One part of the conductive part 16 is formed into a printed wiring part 16A integrally provided by printing a glass 32. With this structure, in the case wherein the light control glass 14 is broken by a collision of a vehicle or the like, the printed wiring part 16A is cut, and application of voltage to the light control glass 14 is thereby stopped.
