HEAT GENERATION ELEMENT AND METHOD FOR PRODUCING SAME

摘要

The purpose of the present invention is to provide a heat generation element having high durability and a method for producing this heat generation element. A heat generation element 1 according to the present invention comprises a first layer 2 that has a tantalum metal phase and a second layer 3 that covers the periphery of the first layer 2 and has a tantalum carbide phase. The silicon concentration in an interface part 4 between the first layer 2 and the second layer 3 is higher than the silicon concentrations in portions other than the interface part 4.
