Abstract: An epoxy material that provides a cured product having a reduced modulus of elasticity and thereby maintaining reliability even under conditions of wide environmental variation. The epoxy resin composition provided includes (A) an epoxy compound A of formula (1) below, (B) phenyl glycidyl ether substituted with a C6-20 hydrocarbon group, and (C) a curing agent. In formula (1), R1 and R2 each independently represent C2-4 alkylene; R3 represents methylene or —C(CH3)2—; and a and b each independently represent a number of 1 to 10.
