A surface mounting method includes applying an active resin composition to at least part of a surface of a printed wiring substrate; mounting a surface mount device on the substrate; performing reflow soldering; applying an under-filling resin into a space of interest; before and/or after applying the under-filling resin, performing a vacuum treatment and/or heating at a temperature lower than the curing reaction-initiating temperature of any of the applied active resin composition and the under-filling resin; and subsequently, thermally curing the resin composition and the under-filling resin. The active resin composition contains an epoxy resin in an amount of 100 parts by weight, a blocked carboxylic acid compound in an amount of 1-50 parts by weight and/or a carboxylic acid compound in an amount of 1-10 parts by weight, and a curing agent which can initiate curing reaction at 150° C. or higher, in an amount of 1-30 parts by weight.
