Disclosed is an electrolytic capacitor which has a long life and which is provided with an electrolyte which is difficult to steam and disperse in butyl rubber used as a sealing member, and which suppresses evaporation volatilization of the electrolyte. An electrolytic capacitor is provided with a capacitor element having an anode foil, a cathode foil and a separator, an electrolytic solution containing a solvent and a solute, a case containing the capacitor element, and butyl rubber sealing the case, wherein the distance between the Hansen solubility parameter of the solvent and the Hansen solubility parameter of the butyl rubber is not less than 26.5, and the boiling point of the solvent is not less than 160 degrees celsius.

Provided is an oxygen reduction catalyst having an excellent oxygen reduction catalytic activity and a selection method thereof, a liquid composition or electrode containing an oxygen reduction catalyst, and an air battery or fuel cell provided with the electrode. An oxygen reduction catalyst containing a metal complex and a conductive material and having an ionization potential value of 5.80 eV or lower and a selection method thereof, a liquid composition or electrode containing an oxygen reduction catalyst, and an air battery or fuel cell provided with electrode.

An information processing apparatus (50) capable of calculating an appropriate route for a vessel (1) including a wind power propulsion unit (10, 10A, 10B, 10C, 10D) configured to propel a hull (11) by wind power, and a vessel (1) is provided. An information acquisition unit (51) acquires area information that is created based on the operation information acquired in each area by another vessel (1B) and includes information relating to at least one of weather and hydrographic condition in the area. Since the area information is information based on an actual operation information of another vessel (1B), the area information more accurately indicates a state of the weather and hydrographic condition in each area than the weather / hydrographic condition forecast. Therefore, a route calculation unit (52) can calculate a route suitable for propulsion by wind power in consideration of the accurate state of weather and hydrographic condition for an area covering a wide range. From the above, it is possible to calculate an appropriate route for the vessel (1) including the wind power propulsion unit (10) configured to propel the hull (11) by wind power.
