Zusammenfassung:	To provide an epoxy resin excellent in low hygroscopicity, heat resistance, flexibility, solvent solubility, and dielectric properties.SOLUTION: A terminal diglycidyl compound is an epoxy resin with an epoxy equivalent of 200-50,000 g/equiv., where the epoxy resin has an alkylene glycol chain having up to 30 of repeating units, having two benzene rings or alkylene ethers. Bonds of the benzene ring comprise a direct bond, a C1-13 divalent hydrocarbon group, -O-, -S-, -SO-, -C(CF)- or -CO-, and comprise a C2-20 divalent hydrocarbon group.SELECTED DRAWING: None 【課題】低吸湿性、耐熱性、可撓性、溶剤溶解性、誘電特性に優れたエポキシ樹脂を提供する。【解決手段】エポキシ当量が２００〜５０，０００ｇ／当量のエポキシ樹脂であり、該エポキシ樹脂が、２個のベンゼン環を含むか、又はアルキレンエーテルを含む、３０迄の操り返し単位からなるアルキレングリコール鎖を有する、末端ジグラシジル化合物。前記ベンゼン環の結合が、直接結合、炭素数１〜１３の２価の炭化水素基、−Ｏ−、−Ｓ−、−ＳＯ２−、−Ｃ（ＣＦ３）２−又は−ＣＯ−からなる、及び炭素数２〜２０の２価の炭化水素基からなる、エポキシ樹脂。【選択図】なし
