<p><P>PROBLEM TO BE SOLVED: To provide a resistor having the structure, in which a metal plate material is sealed with a protecting film for cooling purpose, and the metal plate material can be readily inspected visual as to whether it is exposed from a protective film. <P>SOLUTION: The resistor is provided with a resistance material 11, a couple of electrodes 12, 13 connected to the resistance material, a metal plate material 16 bonded to the resistance material via an insulating layer 15, and a protecting film 18 covering the metal plate material. This resistor is also provided, at the protecting film thereof, with a hole 19 or a groove 21, to a degree of not causing dummy holes for contact the metal plate material on the occasion of the plating process, in which a part of the metal plate material is exposed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
