The present invention relates to a near-infrared irradiation type sealing material capable of suitably joining a member made of resin, glass or the like by irradiating near-infrared rays with a laser, and a bonded product obtained using the sealing material, and An object of the present invention is to provide a method for adhering a member, and a near-infrared irradiation type sealing material of the present invention includes a near-infrared absorbent containing at least a phosphonic acid copper salt represented by the following general formula (1), a resin and a polymerization And at least one component selected from compounds that become polymers. In the formula, R 1 is a monovalent group represented by —CH 2 CH 2 —R 11 , and R 11 is a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, or a fluorinated group having 1 to 20 carbon atoms. An alkyl group is shown. |
