The present invention relates to a thermosetting resin composition containing an inorganic filler (A
1
) containing a nanofiller (a), a thermosetting resin (B), and an elastomer (C); and a thermosetting resin composition containing an inorganic filler (A
2
), a thermosetting resin (B), and an elastomer (C), wherein the inorganic filler (A
2
) has at least two peaks of a first peak and a second peak in a particle size distribution measured according to the laser diffraction scattering method, and a peak position of the first peak appears at 0.3 to 0.7 μm, while a peak position of the second peak appears at 0.7 to 1.2 μm.
