To realize constituent elements for realizing a nonaqueous secondary battery having high energy density and high repeating stability, and a nonaqueous secondary battery using the same. Heat sinks coupled to heat-generating components via thermal interface materials are also described. Upon receiving a request for providing the traffic information from a navigation system of a vehicle the traffic information server transmits the information on the time required for traveling in each traveling direction or the information on the time required for traveling on each route in the branch point area generated from the above information. The two wavelength conversion modules respectively convert the corresponding partial excitation beam coming from the first dichroic unit and the second dichroic unit into two converted beams. Chalcogenide material is disposed over the plated electrode and subjected to a conversion process so that ions from the plated material diffuse into the chalcogenide material.
