Abstract

A resin composition for a circuit board, containing a melt-fabricable fluororesin and a particulate boron nitride. The particulate boron nitride has a ratio (b)/(a) of 1.0 or higher, wherein (a) represents a proportion of particles having a particle size of 14.6 to 20.6 μm and (b) represents a proportion of particles having a particle size of 24.6 to 29.4 μm. Also disclosed is a molded article for a circuit board obtained from the resin composition, a laminate for a circuit board including a metal layer (A1) and a layer (B) obtained from the resin composition, and a circuit board including a metal layer (A2) and a layer (B) obtained from the resin composition.
