Abstract: A side-filling resin composition is used to form a side-filling member to be interposed between a base member and a peripheral edge portion of a surface, facing the base member, of a mounted component that is surface-mounted on the base member. The side-filling resin composition contains a cationic polymerizable component and a photo-cationic polymerization initiator. The cationic polymerizable component includes at least one compound selected from an oxetane compound and an alicyclic epoxy compound. Proportion by mass of the oxetane compound and the alicyclic epoxy compound to a total content of the cationic polymerizable component is equal to or greater than 70% by mass.

Abstract: A side-filling resin composition is used to form a side-filling member to be interposed between a base member and a peripheral edge portion of a surface, facing the base member, of a mounted component that is surface-mounted on the base member. The side-filling resin composition has photocurability.
