This two-sided adhesive tape having different adhesiveness on the front and back can be produced thinly by a simple method, and comprises an adhesive agent composition containing a resin composition and an inorganic filler cured into a sheet. The resin composition contains (A) an acrylate monomer, (B) a monomer co-polymerizable with (A), (C) a photopolymerization initiator, and (D) a photo-crosslinking agent. The inorganic filler has an average particle diameter or 30[mu]m or less, and is unevenly distributed to one side of the tape. The surface roughness (center line average roughness Ra) of the side of the tape surface to which the inorganic filler has been unevenly distributed is 0.01-0.50[mu]m. |
