PROBLEM TO BE SOLVED: To achieve a higher completion degree of a structure of a secondary light-condensing part in a light-condensing type photovoltaic power generation unit.;SOLUTION: When a primary light-condensing part is referred to be on an upper side with respect to a secondary light-condensing part with regard to a vertical relationship of positions on an optical path, the secondary light-condensing part 16 includes: a secondary lens 18 disposed above a power generation element 20; a lens support part 17a that is a pedestal enclosing the power generation element 20 and mounting the secondary lens 18 thereon and supports the secondary lens 18 as floating above the power generation element 20; a light-transmitting coating part 22c made of a resin and covering the surface of the secondary lens 18; and a light-transmitting sealing part 22s made of a resin and filling a gap space between the power generation element 20 and the secondary lens 18 in the lens support part 17a. An upper end face of the lens support part 17a has an inside edge 17e in contact with the secondary lens 18 and a resin receiving part 17r outwardly spreading from the inside edge 17e without contacting the secondary lens 18 and receiving a lower end of the coating part 22c.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2017,JPO&INPIT
