PURPOSE: To make the end treatment of an amorphous metal core easily and prevent the core from getting out of shape in the following thermal treatment process by a method wherein an amorphous metal tape is wound and held by a heat resistant plastic tape on its circumference and processed by thermal treatment.
CONSTITUTION: An amorphous metal tape is wound and held by a heat resistant plastic tape on its circumference and processed by thermal treatment. The amorphous metal tape is insulated by magnesium oxide and a polyimide tape coated by adhesive on one side is used as the heat resistant tape. Amorphous metal has excellent magnetic characteristics but its end treatment after winding is difficult to be performed well and the wound tape is easy to get out of shape. Above manufacturing method solves such weak points and the end treatment of the tape becomes easy and the peeling off in the following thermal treatment process is avoided.
