Insulating adhesive film, prepreg, laminate, cured article, and composite article

An insulating adhesive film having

• a plateable layer which is comprised of a plateable layer-use resin composition which contains a polar group-containing alicyclic olefin polymer (A1) and a curing agent (A2) and
• an adhesive layer which is comprised of an adhesive layer-use resin composition which contains a polar group-containing alicyclic olefin polymer (B1), a curing agent (B2), and an inorganic filler (B3), wherein
• a ratio of content of said polar group-containing alicyclic olefin polymer (A1) to the solid content as a whole which is contained in said plateable layer is 50 to 90 wt %, and
• a ratio of content of said polar group-containing alicyclic olefin polymer (B1) to the solid content as a whole which is contained in said adhesive layer is 1 to 30 wt % and a ratio of content of said inorganic filler (B3) is 50 to 90 wt %.
