摘要

PROBLEM TO BE SOLVED: To provide a laminate which has excellent thermal conductivity, heat resistance, drill workability and flame retardancy.

SOLUTION: In a prepreg obtained by impregnating a woven or nonwoven fabric base with a thermosetting resin composition, the thermosetting resin composition contains 80-200 parts by volume of an inorganic filler per 100 parts by volume of a thermosetting resin, the inorganic filler contains (A) gibbsite type aluminum hydroxide particles having an average particle diameter (D50) of 2-15 μm and (B) magnesium oxide having average particle diameter (D50) of 0.5-15 μm, and the blending ratio (volume ratio) of the gibbsite type aluminum hydroxide particles (A) to the magnesium oxide (B) is 1:0.3-3.
