An adhesion assembly method of an article, in which a plurality of members (2, 3, 4) are joined with an adhesive agent having a chain-reacting curing reaction function that is disposed at joining portions (2a, 3a, 4a) of the members (2, 3, 4), thereby assembling the article, comprising: a first adhesive-agent disposition step of disposing the adhesive agent at a joining portion of at least one of the members; and a first trigger-application cure step of curing said adhesive agent disposed at the joining portion of at least one of the members by applying a first trigger energy for causing a chain-reacting curing reaction of the adhesive agent at a first specified point of the adhesive agent in a state in which a joining portion of another member at least partly overlaps the joining portion of said member at which the adhesive agent is disposed, thereby joining a pair of members (2, 3), a second adhesive-agent disposition step of disposing the adhesive agent at a joining portion of a different member which is to be joined to said pair of members (2, 3) and/or a joining portion of said pair of members (2, 3) which is to be joined to the joining portion of the different member; and a second trigger-application cure step of curing said adhesive agent disposed at the joining portion of said different member and/or the joining portion of said pair of members (2, 3) by applying a second trigger energy for causing a chain-reacting curing reaction of the adhesive agent at a second specified point of the adhesive agent, thereby joining said different member to said pair of members (2, 3), wherein said second specified point of the adhesive agent where the second trigger energy is applied is configured such that a terminal portion of a first chain-reacting cure area of the adhesive agent which is presumed to be generated by applying said first trigger energy to the adhesive agent of the pair of members (2, 3) at least partly overlaps a start portion of a second chain-reacting cure area of the adhesive agent which is to be generated by applying said second trigger energy to the adhesive agent between the pair of members (2, 3) and the different member, and wherein the first trigger energy and the second trigger energy are heat energy or light energy, wherein, if light energy is applied, a notch is formed at the respective joining portions (2a, 3a, 4a) through which the adhesive agent is exposed. a first adhesive-agent disposition step of disposing the adhesive agent at a joining portion of at least one of the members; and a first trigger-application cure step of curing said adhesive agent disposed at the joining portion of at least one of the members by applying a first trigger energy for causing a chain-reacting curing reaction of the adhesive agent at a first specified point of the adhesive agent in a state in which a joining portion of another member at least partly overlaps the joining portion of said member at which the adhesive agent is disposed, thereby joining a pair of members (2, 3), a second adhesive-agent disposition step of disposing the adhesive agent at a joining portion of a different member which is to be joined to said pair of members (2, 3) and/or a joining portion of said pair of members (2, 3) which is to be joined to the joining portion of the different member; and a second trigger-application cure step of curing said adhesive agent disposed at the joining portion of said different member and/or the joining portion of said pair of members (2, 3) by applying a second trigger energy for causing a chain-reacting curing reaction of the adhesive agent at a second specified point of the adhesive agent, thereby joining said different member to said pair of members (2, 3), wherein said second specified point of the adhesive agent where the second trigger energy is applied is configured such that a terminal portion of a first chain-reacting cure area of the adhesive agent which is presumed to be generated by applying said first trigger energy to the adhesive agent of the pair of members (2, 3) at least partly overlaps a start portion of a second chain-reacting cure area of the adhesive agent which is to be generated by applying said second trigger energy to the adhesive agent between the pair of members (2, 3) and the different member, and wherein the first trigger energy and the second trigger energy are heat energy or light energy, wherein, if light energy is applied, a notch is formed at the respective joining portions (2a, 3a, 4a) through which the adhesive agent is exposed.
