Abstract:
A terminal structure of a chip-like electric component capable of blocking entry of electromigration-causing factors through an insulating resin layer in the vicinity of the peak of a raised portion of an electrical element forming layer is obtained. A metal-glaze-based front electrode 103 containing silver is provided on a surface of an insulating ceramic substrate 101. A resistor layer 107 electrically connected to the front electrode 103 is provided on the substrate surface. A glass layer 109a is provided to completely cover a surface of the resistor layer 107 as well as a surface of an end portion of the resistor layer 107 and also to partially cover the front electrode 103. An insulating resin layer 109b is provided to cover a surface of the glass layer 109a as well as a surface of at least an end portion of the glass layer 109a and to partially cover the front electrode 103. A conductive layer 117 made of a resin-based conductive paint is provided to extend over the surface of the front electrode 103 and an portion of the insulating resin layer 109b in the vicinity of the peak of raised end portion of the insulating resin layer 109b. The resin-based conductive paint is made by kneading particulate conductive silver powder and scale-like conductive silver powder into an epoxy-based insulating resin paint.
