Abstract
A thermally conductive sheet of the present invention includes a thermosetting resin (A) and an inorganic filler material (B) that is dispersed in the thermosetting resin (A). In the thermally conductive sheet of the present invention, at a frequency of 1 kHz and at a temperature of 100° C. to 175° C., the maximum value of a dielectric loss factor of a cured product of the thermally conductive sheet is less than or equal to 0.030, and a change in relative dielectric constant of the cured product of the thermally conductive sheet is less than or equal to 0.10.
