Abstract:
Provided is a thermosetting adhesive sheet having a thermosetting adhesive agent layer which, after being cured, can achieve excellent adhesiveness and extremely high heat resistance after exposure to humidity and heat. This thermosetting adhesive sheet is characterized by having a thermosetting adhesive agent layer that is formed from a thermosetting adhesive agent composition containing an acrylic polymer (X), an etherified phenolic resin (Y), and a silica filler (Z1) and/or a copper filler (Z2).
