Provided is a heat exchange element that suppresses an increase in air-flow resistance by suppressing deflection of a partition member caused by a change in temperature and humidity. The unit constituent members are stacked, each of which is formed of partition members that have heat-transfer properties and moisture permeability, and spacing members that hold the partition members. A primary air flow that passes along an upper-surface side of the partition member and a secondary air flow that passes along an undersurface side of the partition member cross each other so as to exchange heat and moisture via the partition member. The spacing member includes: spacing ribs that maintain the spacing between the partition members; and deflection suppressing ribs that have a height smaller than the spacing ribs so as to suppress deflection of the partition members.

An electric double-layer capacitor includes: a positive electrode containing a carbon material; a negative electrode containing a carbon material and a titanium oxide; and an electrolytic solution containing an ammonium salt. A weight ratio of the titanium oxide to the carbon material contained in the negative electrode is 2% by weight or more but not more than 50% by weight.

A porous electrolytic solution reservoir which is capable of being impregnated with an electrolytic solution is provided in an exterior case so as to make contact with a separator. The average diameter of the pores in the electrolytic solution reservoir is greater than the average diameter of pores in the separator. The electrolytic solution reservoir is impregnated with a predetermined amount of electrolytic solution, so that the occupation ratio of electrolytic solution within the pores in the separator becomes 50% or more when fully charged, and the occupation ratio of electrolytic solution within the pores in the electrolytic solution reservoir becomes 100% or less when fully discharged.
