However, the transfer adhesiveness of the low melting point metal film to the transfer target is not sufficient, and after the low melting point metal film is pressed against the transfer target, the transfer sheet is peeled off and the transfer adhesion force by the pressing causes the pressing. It was not possible to complete the transfer while cutting the low-melting point metal film at the boundary between the pressed portion and the non-pressed portion without involving any portion. Therefore, it is necessary to transfer the part that has been transferred from the low-melting-point metal film in a state where it is torn off, and transfer accuracy, especially fine lines, etc. However, it was difficult to improve the transfer accuracy in the fine pattern of.

That is, by pressing the metal film against the transferred material and then peeling off the transfer sheet, the transfer film does not accompany the pressed portion due to the transfer adhesion force by the pressing, and thus the metal film (at the boundary between the pressed portion and the non-pressed portion). The transfer can be completed while cutting the intermediate layer (including the intermediate layer). The pressing portion of the transfer sheet is determined according to the metal film portion to be transferred, that is, the required transfer pattern. The pressing force is not less than the interfacial adhesive force of the metal film or the intermediate layer with respect to the easily peelable sheet to 30 kg / cm 2 or less, and especially 0.

The adhesion of each metal film to the easily peelable sheet at room temperature (180 degree peeling, peeling speed 300 mm / min) was 6 g / cm for indium film, 9 g / cm for bismuth film, and 7 g for tin film, respectively.
/ Cm, 6 g / cm for the lead film and 6 g / cm for the gold film. ◯: When the metal film was not transferred to the adhesive tape and no peeling part was observed in the metal film transferred onto the base substrate. X: When the metal film was peeled off from the base substrate and transferred to the adhesive tape.
