To provide a photo-curing composition that has excellent anti-iodine and anti-solvent properties, can be adhered to electroconductive base plate, has the flexibility corresponding to the plastic film type dye-sensitization solar cell and is screen printable and provide a dye-sensitization type solar cell in which the electrolyte solution is sealed in by using the photo-curing composition.

The photo-curing composition comprises the monomer component including isobornyl acrylate and 4 to 18C alkyl (meth)acrylate, saturated thermoplastic elastomer and a photo-polymerization initiator, wherein the weight ratio of isobornyl acrylate to alkyl (meth)acrylate is 20 : 80 to 70 : 30 and has a viscosity 5 to 4,000 Pas measured at 20°C under the shear rate of 1 sec-1. The dye-sensitization type solar cell in which the electrolyte solution is sealed in by using the photo-curing composition as a sealing material and a method for production thereof.
