See full text

The present invention relates to an adhesive film for a multilayer printed-wiring board, in which a property of filling irregularities is excellent even when silica filler is highly filled. Specifically, there is provided an adhesive film for a multilayer printed-wiring board, which includes a resin composition layer that is obtained by forming a layer of a resin composition containing: (A) a novolac type phenolic resin in which a dispersity (Mw/Mn) of a weight average molecular weight (Mw) and a number average molecular weight (Mn) ranges from 1.05 to 1.8; (B) an epoxy resin represented by general formula (1); and (C) inorganic filler, on a support film. An average particle size of the (C) inorganic filler in the resin composition layer is 0.1 μm or more, and a content of the (C) inorganic filler in a resin solid content ranges from 20% to 95% by mass.
