Claim 8:
9. The adhesive composition for use in debonding with light irradiation according to claim 1, wherein the component (S) which is cured through hydrosilylation comprises a polysiloxane (A1) having one or more units selected from the group consisting of a siloxane unit represented by SiO2 (unit Q), a siloxane unit represented by R1R2R3SiO1/2 (unit M), a siloxane unit represented by R4R5SiO2/2 (unit D), and a siloxane unit represented by R6SiO3/2 (unit T), wherein each of R1 to R6 is a group or an atom bonded to a silicon atom and represents an alkyl group, an alkenyl group, or a hydrogen atom, and a platinum group metal catalyst (A2); and
the polysiloxane (A1) comprises:
a polyorganosiloxane (a1) having one or more units selected from the group consisting of a siloxane unit represented by SiO2 (unit Q′), a siloxane unit represented by R1′ R2′ R3′ SiO1/2 (unit M′), a siloxane unit represented by R4′ R5′ SiO2/2 (unit D′), and a siloxane unit represented by R6′ SiO3/2 (unit T′), and at least one unit selected from the group consisting of unit M′, unit D′, and unit T′, wherein each of R1′ to R6′ is a group bonded to a silicon atom and represents an alkyl group or an alkenyl group, and at least one of R1′ to R6′ is an alkenyl group, and

a polyorganosiloxane (a2) having one or more units selected from the group consisting of a siloxane unit represented by SiO2 (unit Q″), a siloxane unit represented by R1″ R2″ R3″ SiO1/2 (unit M″), a siloxane unit represented by R4″ R5″ SiO2/2 (unit D″), and a siloxane unit represented by R6″ SiO3/2 (unit T″), and at least one unit selected from the group consisting of unit M″, unit D″, and unit T″, wherein each of R1″ to R6″ is a group or an atom bonded to a silicon atom and represents an alkyl group or a hydrogen atom, and at least one of R1″ to R6″ is a hydrogen atom.
