NOVELTY - An adhesive seal material (1) for an end portion a frameless solar cell module (7) which is bonded to an end portion of a frameless solar cell module comprises a base material (2); and an adhesive layer (3) formed on a surface of the base material, where the base material includes a reinforcement layer (4) having a top surface on which the adhesive layer is laminated; and a barrier layer (5) formed on a back surface of the reinforcement layer.    USE - As an adhesive seal material for an end portion a frameless solar cell module (claimed).    ADVANTAGE - The adhesive seal material is easily bonded to an end portion of a frameless solar cell module, has excellent adhesion to the frameless solar cell module, has an excellent water vapor barrier property as well as excellent light resistance, weathering resistance, and heat resistance, and exhibits an excellent cushioning property to its surroundings, frameless solar cell module using the adhesive seal material, and sealed structure of an end portion.    DETAILED DESCRIPTION - An adhesive seal material (1) for an end portion a frameless solar cell module which is bonded to an end portion of a frameless solar cell module comprises a base material (2); and an adhesive layer (3) formed on a surface of the base material, where the base material includes a reinforcement layer (4) having a top surface on which the adhesive layer is laminated; and a barrier layer (5) formed on a back surface of the reinforcement layer. The reinforcement layer is a split-fiber non-woven fabric. The adhesive layer is made of a butyl-based adhesive composition. The adhesive seal material further comprises protective layer formed on the back surface of the barrier layer to protect the adhesive seal material for the end portion of the frameless solar cell module. INDEPENDENT CLAIMS are included for the following:    (1) frameless solar cell module, where, to an end portion, bonded is an adhesive layer of an adhesive seal material for the end portion of the frameless solar cell module, comprising: a base material, and the adhesive layer formed on a surface of the base material, where the base material includes reinforcement layer having a top surface on which the adhesive layer is laminated, and a barrier layer formed on a back surface of the reinforcement layer; and    (2) sealed structure of an end portion of a frameless solar cell module, where, to the end portion of the frameless solar cell module, bonded is an adhesive seal material for the end portion of the frameless solar cell module, comprising base material; and an adhesive layer formed on a surface of the base material, where the base material includes a reinforcement layer having a top surface on which the adhesive layer is laminated; and a barrier layer formed on a back surface of the reinforcement layer.
