PROBLEM TO BE SOLVED: To remarkably reduce damages of electric parts in carrying and mounting the electronic parts, and to greatly improve the positional accuracy of the electronic parts by constituting an electronic parts carrier tape of a heating-and-peeling type adhesive sheet having a specified heat expansible layer. SOLUTION: A heat expansible adhesive layer 3 including heat expansible small balls is provided on one surface of a base material 1 through a rubber-like organic elastic layer 2, and a separator 4 is laminated thereon to constitute a heating and peeling type adhesive sheet A. The heat expansible small balls may include small balls in which a substance heated to easily gasify and expand such as isobutane, propane and pentane is encapsulated in an elastic shell. Since the electronic parts are adhered and fixed to an adhesive surface, damages during the carriage and storage are prevented, and when heated, the heat expansive adhesive layer 3 is expanded, and the adhesive force to the electronic parts is rapidly degraded, and the electronic parts can be detached from the tape without applying unreasonable force. |
