Provided is a transparent conductor 10 comprising a transparent substrate 11, a first metal oxide layer 12, a metal layer 18 including a silver alloy, a third metal oxide layer 14, and a second metal oxide layer 16 in this order. The first metal oxide layer 12 is constituted by a metal oxide other than ITO, the second metal oxide layer 16 includes ITO, and the work function of a surface 16a of the second metal oxide layer 16 on the opposite side to the metal layer 18 side is 4.5 eV or higher. L'invention concerne un conducteur transparent 10 comprenant un substrat transparent 11, une première couche d'oxyde métallique 12, une couche métallique 18 comprenant un alliage d'argent, une troisième couche d'oxyde métallique 14 et une seconde couche d'oxyde métallique 16 dans cet ordre. La première couche d'oxyde métallique 12 est constituée d'un oxyde métallique autre que l'ITO, la seconde couche d'oxyde métallique 16 comprend de l'ITO, et la fonction de travail d'une surface 16a de la seconde couche d'oxyde métallique 16 sur le côté opposé au côté de la couche métallique 18 est supérieure ou égale à 4,5 eV. 透明導電体１０は、透明基材１１と、第１の金属酸化物層１２と、銀合金を含む金属層１８と、第３の金属酸化物層１４と、第２の金属酸化物層１６と、をこの順で備える。第１の金属酸化物層１２は、ＩＴＯとは異なる金属酸化物で構成され、第２の金属酸化物層１６は、ＩＴＯを含有し、第２の金属酸化物層１６の金属層１８側とは反対側の表面１６ａの仕事関数が４．５ｅＶ以上である。
