摘要: The invention refers to a manufacturing method of an EL insert molding which can manufacture the EL element without damage while a temperature and a pressure of resin to be injected are maintained on an optimum forming condition, wherein a luminous portion 3A and a non-luminous portion 3B are provided in an EL element 3. The EL element 3 is inserted in a cavity 15 of an injection die, resin is injected into the cavity to manufacture the EL insert molding. In the cavity 15, a gate portion 18 is provided at a position opposite to the non-luminous portion 3B of the EL element 3. A decorative film 2 may be formed integrally in front of the EL element 3.
