There is provided a concentrator photovoltaic unit and apparatus in which light collecting efficiency is hardly reduced and sealing ability is hardly deteriorated while using a resin lens and a metal case. After attaching a homogenizer (3) and a photovoltaic element (4) a holding member (5), a Fresnel lens (2) is attached to a case (6) to close an opening at an upper end portion of the case (6), and the holding member (5) is attached to the case (6) to close an opening at a lower end portion of the case (6), so that one concentrator photovoltaic unit (1) in which the photovoltaic element is accommodated is manufactured. |
