A thermosetting sheet according to the present invention includes: a thermosetting resin; a thermoplastic resin; and conductive particles. The conductive particles includes silver particles having an average particle size D 50 of 0.01 µm or more and 10 µm or less, and having a circularity in cross section of 0.7 or more. The thermosetting sheet has a viscosity at 100 °C of 20 kPa·s or more and 3000 kPa·s or less. |
