Disclosed are an organic electroluminescent element with a light-transmitting electrode having reduced resistivity and emitting a uniform amount of light from the surface, and an associated lighting device. The organic EL element includes: a light-transmitting electrode layer provided on a light-transmitting substrate; an electrode layer forming a pair with the light-transmitting electrode layer; an organic layer between the electrode layers, containing an organic electroluminescent substance; a light-blocking auxiliary electrode formed on the light-transmitting electrode layer in contact with a part of the light-transmitting electrode layer; and an insulating coating film covering the auxiliary electrode. The auxiliary electrode has a low resistivity layer formed from a low resistivity material with a low specific resistance relative to the light-transmitting electrode layer and a coating layer formed from a high melting point material with a higher melting point than the low resistivity material.
