SHEET-SHAPED HEATING ELEMENT AND METHOD FOR PREPARING THE SAME

摘要

Disclosed are a sheet-shaped heating element, which has the advantages of excellent attachability and no lateral displacement of a heat generating composition due to its load, and a method for preparing the same. The sheet-shaped heating element is characterized in that the film or sheet is formed with multiple cells having a height of 0.1-50 mm, a width of 1-100 mm and a distance between cells of 0.1-50 mm, and an oxidizable metal powder-containing heat generating composition is filled in the cells, and a pressure sensitive adhesive or a pharmacologically active material-containing adhesive matrix is attached to the bottom face of the heating element. Such flexible heating element can be attached to bendable portions of humans or animals and is not detached even after the heat generating composition is cured.
