To provide a pigment-sensitivity-enhanced optoelectronic transducer and a optoelectronic chemical battery which are excellent in a optoelectronic transducer characteristic and durability by the use of a simple manufacturing process.

In this optoelectronic transducer that has a conductive supporting body, a semiconductor fine-particle containing layer that has adsorbed pigment applied to the surface of the conductive supporting body, a charge transferring layer and a couple of electrodes, and is enhanced in pigment sensitivity. This optoelectronic transducer is featured in the charge transfer layer containing a gel electrolyte containing a product provided by reacting a polymer having a hydroxyl group and/or a carboxyl group with a compound having at least two or more isocyanate groups, and this optoelectronic chemical battery uses the transducer.
