An adhesive containing at least two main components, and which is capable of being gelled to make it pressure-sensitive, of being photopolymerized and of being thermally polymerized, is applied at selected positions on a printed circuit substrate on which electronic parts are to be loaded. Ultraviolet rays are irradiated on the adhesive, to gelate the adhesive thereby to realize the pressure-sensitive adhesion ability by reaction of a photopolymerization functional group of the adhesive. After loading the electronic parts on the adhesive, the adhesive is hardened by reaction of a thermal polymerization functional group by heating. Thereafter, electrodes of the electronic parts and conductive lands of the printed circuit substrate are soldered.
