Claim:
A terminal structure of a chip-like electric component that includes: a metal-glaze-based front electrode containing silver, said front electrode being provided on a surface of an insulating ceramic substrate; an electrical element forming layer electrically connected to the front electrode and formed on the surface of the substrate; an electrically-insulating protective layer including a glass layer that covers the electrical element forming layer, and an insulating resin layer that covers the glass layer and partially covers the front electrode; the glass layer completely covering a surface of the electrical element forming layer as well as a surface of an end portion of the electrical element forming layer, and also partially covering the front electrode; the insulating resin layer completely covering a surface of the glass layer as well as a surface of an end portion of the glass layer, and also partially covering the front electrode, the insulating resin layer having a raised end portion; a conductive layer formed of a resin-based conductive paint, and provided to extend in the vicinity of a peak of the end raised portion of the insulating resin layer and also to extend over the surface of the front electrode; and at least one conductive thin film layer that forms an interface with a surface of the insulating resin layer, and is formed, via the conductive layer, above a portion of the front electrode that is not covered with the insulating resin layer, wherein the resin-based conductive paint is made by kneading particulate conductive silver powder and scale-like conductive silver powder into a xylene-phenol-based resin selected from epoxy-based resins and having a viscosity of 40 to 80 Pa·s; the particulate conductive silver powder has a particle size of 0.8 to 1 μm and the scale-like conductive silver powder has a longer-side size of 10 to 15 μm; a compounding ratio of the particulate conductive silver powder to the scale-like conductive silver powder ranges from 6:4 to 9:1; and the length of the overlapped portion between the insulating resin layer and the conductive layer, as measured in the direction where the front electrode and the electrical element forming layer are arranged, is 20 μm or more.
