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) (RO)3—Si-T  (1) wherein R is a monovalent hydrocarbon group, T is a group represented by the formula, —OR1 or —CHR2—COOR3, wherein R1 is a monovalent hydrocarbon group, which may be the same with or different from R, R2 is a hydrogen atom or a methyl group and R3 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.
