Abstract
A lead line terminal part 2a of a lead line 2 for trigger is attached on an outside surface 1b of a reflective umbrella 1 by using a conductive paste 3. That is, the lead line terminal part 2a is placed on the outside surface 1b of the reflective umbrella 1, and the conductive paste is applied. An adhesive tape 4 is stuck on the applied conductive paste 3 and is temporarily fixed. They are put in a heating furnace with the adhesive tape temporarily fixed and the conductive paste 3 is hardened to terminate attachment of the lead line 2a. It is unnecessary to remove the adhesive tape 4, and it is convenient because the lead line part is insulated.
