Abstract: An electrically conductive paste used to form an electrode used for electrical connection to a p-type semiconductor layer of a crystalline silicon solar cell, wherein the electrically conductive paste is able to fire through an antireflective film during firing and is capable of forming an electrode having low contact resistance on a p-type semiconductor layer. The electrically conductive paste contains (A) an electrically conductive powder, (B) Al powder or Al compound powder having an average particle diameter of 0.5 μm to 3.5 μm, (C) a glass frit and (D) an organic medium, and contains 0.5 parts by weight to 5 parts by weight of the Al powder or Al compound powder (B) based on 100 parts by weight of the electrically conductive powder (A).
