| abstract |
An aspect of the present invention is a metal clad laminate comprising: an insulating layer including a cured product of a resin composition containing a polymer having a structural unit represented by formula (1) in the molecule thereof; and a metal foil layered on the insulating layer, wherein, in the metal foil, the amount of elemental nickel in the surface thereof that is in contact with the insulating layer, and the amount of elemental nickel in the surface when the surface is subjected to sputtering for 1 minute at a rate of 3 nm/min. in terms of SiO2, are each 4.5 atom% or less with respect to the amount of all elements in the surface. In formula (1), Z represents an arylene group, R1-R3 each independently represent a hydrogen atom or an alkyl group, and R4-R6 each independently represent a hydrogen atom or an alkyl group having 1-6 carbon atoms. |
