PROBLEM TO BE SOLVED: To provide an epoxy resin composition, which ensures high thixotropic property by including fine powder silica and silyl group terminal polyalkylene oxide resin, and enables visual measurement by setting viscoelastic characteristic value as follows. SOLUTION: The epoxy resin composition comprises fine powder silica and a silyl group terminal polyalkylene oxide resin as a thixotropic property imparting agent. The composition has loss elastic modulus of viscoelastic characteristics of 1,400 Pa or more and phase differenceδof 15°or less. The fine powder silica is hydrophilic. COPYRIGHT: (C)2009,JPO&INPIT
