NOVELTY - An ionic liquid content aggregate (10) has 1st ionic liquid inclusion particle (12) having ionic liquid (16) or solidified material in a 1st package material (18) consists of 1st polymer, and 2nd ionic liquid inclusion particle (14) having ionic liquid or solidified material in a 2nd package material (22) consists of 2nd polymer. The 1st package material of 1st ionic liquid inclusion particle and 2nd package material of 2nd ionic liquid inclusion particle bond together chemically, and reaction product is formed.    USE - Ionic liquid content aggregate for fuel cell, secondary battery, capacitor, and dye-sensitized solar cell.    ADVANTAGE - Even if ionic liquid content aggregate contacts a substance having high affinity to the ionic liquid, flow of ionic liquid to substance is prevented, ion conductivity fall is avoided, favorable power generation characteristic is maintainable over a long period of time, has high plasticity, and molding into desired shape is easy.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing method of ionic liquid content aggregate, dispersing ionic liquid in 1st dispersion medium at a temperature beyond melting point of the ionic liquid to prepare 1st emulsion, lowering the temperature from melting point of ionic liquid of 1st emulsion to temperature beyond melting the point of 1st dispersion medium to obtain solidified material of ionic liquid as 1st particle, separating 1st particle from the dispersion medium, adding to 2nd dispersion medium, forming low temperature 1st package material consists of 1st polymer at a temperature beyond melting point of 2nd dispersion medium rather than melting point of the ionic liquid, on the surface of 1st particle to obtain 1st ionic liquid inclusion particle, dispersing ionic liquid in 3rd dispersion medium at a temperature beyond melting point of ionic liquid to obtain 2nd emulsion, lowering the temperature from melting point of ionic liquid in 2nd emulsion to temperature beyond melting point of 3rd dispersion medium to obtain solidified material of ionic liquid as 2nd particle, separating 2nd particle from the 3rd dispersion medium, adding to 4th dispersion medium, forming low temperature 2nd package material consists of 2nd polymer at temperature beyond melting point of 4th dispersion medium rather than melting point of ionic liquid on the surface of 2nd particle to obtain 2nd ionic liquid inclusion particle, reacting 1st polymer which forms the 1st package material of 1st ionic liquid inclusion particle and 2nd polymer which forms 2nd package material of 2nd ionic liquid inclusion particle in the same solvent, and forming the reaction product of 1st and 2nd polymers to obtain ionic liquid content aggregate while combining 1st package material of 1st ionic liquid inclusion particle and 2nd ionic liquid inclusion particle chemically.
