    • An electrical resistive device in which an element composed of a conductive polymer is positioned in contact with the surface layer of one or more metal electrodes. The metal electrode contains a base layer which includes a first metal, an intermediate metal layer which includes a metal that is different from the first metal, and a surface layer which (i) includes a second metal, (ii) has a center line average roughness {overscore (Ra)} of at least 1.3, and (iii) has a reflection density Rd of at least 0.60. The conductive polymer composition preferably exhibits PTC behavior density requirements, which may be, for example, circuit protection devices or heaters, have improved thermal and electrical performance over devices prepared with electrodes which do not meet the center line average roughness and reflection density requirements.

    • An electrical device (1) in which an element (7) composed of a conductive polymer is positioned in contact with the surface layer of one or more metal electrodes (3,5). The metal electrode contains a base layer (9) which comprises a first metal, an intermediate metal layer (15) which comprises a metal that is different from the first metal, and a surface layer (17) which (i) comprises a second metal, (ii) has a center line average roughness R.sub.a of at least 1.3, and (iii) has a reflection density R.sub.d of at least 0.60. The conductive polymer composition preferably exhibits PTC behavior. The electrical devices, which may be, for example, circuit protection devices or heaters, have improved thermal and electrical performance over devices prepared with electrodes which do not meet the center line average roughness and reflection density requirements.
