  • Patent number: 11830641
    Abstract: A chip resistor component, includes: a substrate having one surface, and one side surface and the other side surface facing each other in one direction; an terminal including an internal electrode disposed on the one surface, and an external electrode disposed on the one side surface to be connected to the internal electrode; a resistive layer disposed on the one surface, and including an outermost pattern connected to the internal electrode; and a protective layer disposed on the one surface to cover the resistive layer. The outermost pattern of the resistive layer has a first region in contact with the internal electrode and a second region extending, in the one direction, from the first region towards the other side surface. A ratio of a length of the second region in the one direction to a length of the chip resistor component in the one direction is 0.02 or more.
