An adhesive composition comprising the following components: (A) a linear polyfluoro compound having at least two SiH bonds per molecule and a perfluoropolyether residue in a main chain of the linear polyfluoro compound (A); (B) an organohydrogensiloxane having a fluorinated group and at least two hydrogen atoms each bonded to a silicon atom per molecule; (C) a compound of a platinum group metal; (D) hydrophobic silica powder; (E) an alkoxysilane represented by the following formula (1) <?in-line-formulae description="In-line Formulae" end="lead"?>(RO)<SUB>3</SUB>-Si-T (1)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R is a monovalent hydrocarbon group, T is a group represented by the formula, -OR<SUP>1 </SUP>or -CHR<SUP>2</SUP>-COOR<SUP>3</SUP>, wherein R<SUP>1 </SUP>is a monovalent hydrocarbon group, which may be the same with or different from R, R<SUP>2 </SUP>is a hydrogen atom or a methyl group and R<SUP>3 </SUP>is a monovalent hydrocarbon group; and (F) an organosiloxane having at least one SiH bond and at least one group selected from the group consisting of an epoxy group and a trialkoxysilyl group. The composition has no quality variation from lot to lot and gives a cured product having good resistance to solvents and heat, and durability.
