摘要： The present invention provides an array type chip resistor including: a substrate formed in a rectangular parallelepiped shape; lower electrodes disposed on both sides of a bottom surface of the substrate at equal spaces; side electrodes extended from some of lower electrodes, formed on outermost edges of both sides of the substrate, in all lower electrodes, to a side surface of the substrate; a resistive element interposed between lower electrodes of the bottom surface of the substrate; a protection layer covered on the resistive element, the protection layer having both sides which cover a part of the lower electrodes and the resistive element; leveling electrodes being in contact with the lower electrodes exposed to outside of the protection layer; and a plating layer formed on the leveling electrodes. The array type chip resistor can prevent the resistive element from being damaged due to external impact when mounted since the resistive element is printed inside of the lower electrodes of the bottom surface of the substrate.
