Patent ID: 7277006

Claim:
A chip resistor including a first substrate having a polygonal flat-panel shape, made of an electrical insulating material and having a first upper surface and a first lower surface, a second substrate having a polygonal flat-panel shape, made of an electrical insulating material and having a second upper surface and a second lower surface, and a joint layer interposed between the first lower surface of the first substrate and the second upper surface of the second substrate and made of an electric insulating material, the chip resistor comprising: first and second electrodes formed on two first opposing sides of the polygonal flat-panel shape of the first substrate; a first electric circuit formed on the first upper surface and/or the first lower surface between the first electrode and the second electrode, and having a predetermined conductivity property or a predetermined electric resistance; third and fourth electrodes formed on two second opposing sides of the polygonal flat-panel shape of the second substrate; a second electric circuit formed on the second upper surface between the third electrode and the fourth electrode, and having a predetermined conductivity property or a predetermined electric resistance; and a gap that shut off electric conductivity, formed between the first and second electrodes and between the second and fourth electrodes, wherein a first direction that connects the two first opposing sides and a second direction that connects the two second opposing sides cross each other while the first substrate and the second substrate stack one on another via the joint layer as viewed from the first upper surface, the first electric circuit and the second electric layer are electrically separated from each other via the joint layer, and the second electric circuit and the second lower surface of the second substrate are set away from each other by a thickness of the second substrate.
