An electroconductive laminate (10) which has a substrate (11) and an electroconductive film (12) formed on the substrate (11), wherein the electroconductive film (12) is a multi-layer structure where oxide layers (12a) and metal layers (12b) are alternately laminated from the substrate (11) side in a total layer number of (2n + 1) (wherein n is an integer of 1 or more) and wherein the oxide layer (12a) contains zinc oxide and a metal oxide having a high refractive index of 2.3 or more as a main component and the metal layer (12b) contains silver or a silver alloy as a main component. The above electroconductive laminate (10) exhibits broad ransmission and reflection bands and is excellent in electromagnetic wave shielding property, visible light transmissivity and near-infrared ray shielding property.

L~invention concerne un stratifié électroconducteur (10) possédant un substrat (11) et un film électroconducteur (12) formé sur le substrat (11), où le film électroconducteur (12) est une structure à couches multiples, des couches d~oxyde (12a) et des couches de métal (12b) étant stratifiées en alternance à partir du côté substrat (11) dans un nombre total de couches de (2n + 1) (où n est un entier supérieur ou égal à 1) et où la couche d~oxyde (12a) contient de l~oxyde de zinc et un oxyde de métal d~un indice de réfraction élevé supérieur ou égal à 2,3 comme composant principal et la couche de métal (12b) contient de l~argent ou un alliage d~argent comme composant principal. Le stratifié électroconducteur (10) ci-dessus possède de larges bandes de transmission et de réflexion et il est excellent en matière de propriété de protection à onde électromagnétique, de transmissivité de lumière visible et de propriété de protection contre les rayons proches de l~infrarouge.
