Abstract: [Object] To provide adhesive composition which allows for preventing misalignment when mutually laminating adherends, mutually strongly bonding the adherends when correction of lamination is not required, as well as peeling the adherends without causing any damage thereto when correction of lamination is required.[Means for achieving the Object] Adhesive composition according to the present invention comprises an adhesive base agent consisting of a monomer and a polymerization initiator. Adhesive strength of the adhesive composition changes to take a local maximum value, a local minimum value and a value greater than the local maximum value along with increase of irradiation amount of the electromagnetic wave or particle beam irradiated to the adhesive composition under a predetermined temperature environment.

Abstract: An objective of the present invention is to provide a brittle material chip and the like having excellent flexibility. The present invention is a brittle material chip including a brittle material layer formed of a brittle material. The brittle material chip includes first processed marks formed on one side in a thickness direction of the brittle material layer on at least one end surface of the brittle material layer and having depths of 1 μm or more and less than half the thickness of the brittle material layer and includes or does not include second processed marks formed on the other side in the thickness direction on the end surface of the brittle material layer, facing the first processed marks in the thickness direction, and having depths of less than 1 μm.
