Abstract
Abstract An electrode structure of a solar cell includes a metal wire fixed to the light incident surface of the solar cell with an electrically conductive adhesive. An electrode production method of a solar cell includes applying an electrically conductive adhesive to at least one of a portion of a metal wire and a portion of the light incident surface of the solar cell, pressing the metal wire into a predetermined position of the light incident surface of the solar cell, and solidifying the conductive adhesive to fix the metal wire.
