摘要： A resin composition contains a polyphenylene ether compound (A) having at least one of a group represented by the following Formula (1) and a group represented by the following Formula (2) in the molecule, a curing agent (B), a titanate compound filler (C), and a silica filler (D), in which the content ratio of the titanate compound filler (C) to the silica filler (D) is 10:90 to 90:10 as a mass ratio.
In Formula (1), p represents 0 to 10, Ar represents an arylene group, and R1 to R3 each independently represent a hydrogen atom or an alkyl group.
In Formula (2), R4 represents a hydrogen atom or an alkyl group.-

摘要： A metal-clad laminate includes an insulating layer, and a metal foil in contact with at least one surface of the insulating layer, in which the insulating layer contains a cured product of a resin composition containing a polyphenylene ether compound, and the metal foil is a metal foil in which a first nickel element amount, on a surface on a side in contact with the insulating layer, measured by X-ray photoelectron spectroscopy is 4.5 at % or less with respect to a total element amount measured by X-ray photoelectron spectroscopy, and a second nickel element amount, on a surface on a side in contact with the insulating layer when the surface is sputtered for 1 minute at a speed of 3 nm/min in terms of SiO2, measured by X-ray photoelectron spectroscopy is 4.5 at % or less with respect to a total element amount measured by X-ray photoelectron spectroscopy.

摘要： A metal-clad laminate includes an insulating layer that contains a cured product of a resin composition containing a polymer having a structural unit represented by Formula (1) in a molecule and a metal foil that is laminated on the insulating layer and is a metal foil in which a nickel element amount on a surface on a side in contact with the insulating layer and a nickel element amount on the surface when the surface is sputtered for 1 minute at 3 nm/min in terms of SiO2 are each 4.5 at % or less with respect to the total element amount on each 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.
