樹脂層13は、約250℃のはんだによる電子素子の実装に耐えられるようにガラス転移温度(Tg)が250℃以上であるのが好ましい。また、樹脂層13は、絶縁性を担保するために絶縁破壊電圧が5kV以上であることが好ましい。さらに、樹脂層13は、熱収縮がほぼないこと、すなわち、熱収縮率が0.1%以下であることが好ましい。
銅層15は、実装基板用放熱積層材1の上に実装される電子素子を配線するための回路をエッチング等により形成するために設けられる。樹脂層13としてのポリイミド樹脂層の上に銅層15としての銅膜を蒸着することにより構成されてもよいが、樹脂層13の上に接着層14を介在して銅層15としての電解銅箔を積層することにより構成されるのが好ましい。

加熱収縮率(%)=((L1-L2)/L1)×100
L1:加熱前の標点間距離(mm)
L2:加熱後の標点間距離(mm)
