<p>PROBLEM TO BE SOLVED: To provide a manufacturing method of a tab lead member by which product yield can be improved by easily heat-welding an insulation film at an accurate position of a lead substrate without complicating a device configuration in a heat-welding device such as a hot press or a heat roll.SOLUTION: In a tab lead member, an insulation film is disposed on both sides of a lead substrate with good conductivity, and the insulation film is fixed at predetermined positions of the lead substrate by heat-welding the insulation film under heat and pressure. A manufacturing method of the tab lead member includes a positioning step of positioning the insulation film by temporarily affixing the insulation film at the predetermined positions on both the sides of the lead substrate prior to a heating/pressing step of heat-welding the insulation film while disposing the insulation film on both the sides of the lead substrate, the insulation film used being a film having on one side an adhesive layer adhesive under normal temperature.</p> |
