To provide an epoxy resin composition (adhesive) which has a sufficient pot life as one pack and is excellent in temporary fixing property and adhesiveness.SOLUTION: An epoxy resin composition comprises: an epoxy resin; a thixotropic agent; a photobase generator; and an ether skeleton polythiol. A content of the photobase generator is 3 to 15 pts.mass with respect to 100 pts.mass of the epoxy resin. The ether skeleton polythiol has 60 to 72 thiol equivalents with respect to 100 epoxy equivalents of the epoxy resin.SELECTED DRAWING: None 【課題】一液で十分な可使時間があり、仮固定性、接着性に優れたエポキシ樹脂組成物（接着剤）を提供する。【解決手段】エポキシ樹脂、チクソ剤、光塩基発生剤、及びエーテル骨格ポリチオールを含むことを特徴とするエポキシ樹脂組成物。前記光塩基発生剤の含有量が、前記エポキシ樹脂１００質量部に対して、３〜１５質量部であり、前記エーテル骨格ポリチオールのチオール当量が、前記エポキシ樹脂のエポキシ１００当量に対して、６０〜７２当量である。【選択図】なし
