More preferably, it is more preferably used in the range of 60 to 150 parts by mass. This is because the flame retardant effect of the inorganic filler (A) is obtained at 5 parts by mass or more, and the drill workability is good at 250 parts by mass or less.
- an inorganic filler other than a mixture of hydromagnesite and huntite can be used in combination.
- the inorganic filler that can be used in combination is not particularly limited as long as it is an inorganic filler that is usually used for printed wiring materials.
- natural silica, fused silica, amorphous silica, hollow silica and other silicas, boehmite, molybdenum oxide And molybdenum compounds such as zinc molybdate, alumina, talc, calcined talc, mica, short glass fibers, spherical glass (glass fine powders such as E glass, T glass, D glass, S glass, and Q glass).
