Claim:
1. A chip resistor device having terminal electrodes, comprising: a substrate, said substrate having a front surface, a back surface and two side surfaces; two front terminal electrodes, said front terminal electrodes being formed on said front surface of said substrate, said front terminal electrodes being separated with each other, said front terminal electrodes being separately aligned along said side surfaces of said substrate; two back terminal electrodes, said back terminal electrodes being formed on said back surface of said substrate, said back terminal electrodes being separated with each other, said back terminal electrodes being separately aligned along said side surfaces of said substrate; a first resistor layer, said first resistor layer being formed on said front surface and located between said front terminal electrodes, a part of each of two ends of said first resistor layer overlapping at least a part of one of said front terminal electrodes separately; a first protector layer, said first protector layer overlapping said first resistor layer, a size of said first protector layer being different from a size of said first resistor layer to obtain an exposed area at each of said two ends of said first resistor layer separately; and two side terminal electrodes, said side terminal electrodes being formed on said side surfaces of said substrate, each of said side terminal electrodes being separately connected to one of said front terminal electrodes at the same side and one of said back terminal electrodes at the same side, a part of each of said side terminal electrodes overlapping said exposed area of each of said two ends of said first resistor layer, wherein a current is directly conducted to said first resistor layer through said side terminal electrodes, wherein said size of said first protector layer is at least 1 micrometer (μm) smaller than said size of said first resistor layer.
