An adhesive composition comprising a siloxane compound (A) which is a hydrolysis condensate (a) of a hydrolysis condensable silane compound represented by the following formula (a1). (in the formula, B represents an alkanediyl group having 1 to 20 carbon atoms or a divalent alicyclic hydrocarbon group having 3 to 20 carbon atoms, and -CH 2 - constituting the alkanediyl group and the alicyclic hydrocarbon group is optionally substituted. It is -O- or -CO-, R 1 and R 2 each independently represent an alkyl group having 1 to 5 carbon atoms, and R 3 , R 4 , R 5 and R 6 each independently represent an alkyl group having 1 to 5 carbon atoms. or alkoxy with 1 to 5 carbon atoms). |
