PURPOSE: To provide a handle for a cooker which can visually inform a user of being heated at a high temperature.

CONSTITUTION: A peeling layer 4 is formed using a peeling ink by a screen printing on the entire surface of a die releasing base body sheet and a thermosensitive discoloring layer 2 is formed on the entire surface of the peeling layer 4 by a screen printing using a black thermosensitive discoloring ink that vanishes in color by heating it up to 60°C. Then, a non-discoloring layer 3 is formed on the thermosensitive discoloring layer 2 by a screen printing using a red non-discoloring ink to indicate a warning against overheating 'HOT !!' and an adhesive layer 5 is formed entirely on the thermosensitive discoloring layer 2 and the non-discoloring layer 3 using an adhesive ink by a gravure printing to obtain a transfer material. The transfer material thus obtained is laminated with the adhesive layer 5 side thereof facing the surface of a dark gray handle 1 for a cooker, and then, bonded on the handle 1 for the cooker by heating and pressurizing it with a silicone rubber transfer pad from the side of the base body sheet of the transfer material and base body sheet is peeled off to provide a thermal discoloring layer on the surface of the handle 1 for the cooker.
