The present invention relates to a novel reactive functional group containing a siloxane (A), a hardening resin composition including the siloxane (A) and a hardening agent (B), and an optical semiconductor component (such as LED) hermetically sealed by a hardened substance thereof, wherein the hermetically sealed optical semiconductor component demonstrates excellent resistance to light and low elasticity at low temperature. The siloxane (A) is a block-type siloxane oligomer having a chain of silicone segment and a hydrolysis and condensation segment of trialkoxysilane (C1-C10) containing a group selected from the group consisting of epoxy-containing reactive functional group, methyl, and ethyl, wherein at least a portion of the hydrolysis and condensation segment contains at least an epoxy-containing reactive functional group. The siloxane is obtained by the first step reaction and the ensuing second step reaction described hereunder. 1st step reaction: Reacting the siloxane compound in the condition that t
