Abstract:
1. A chip resistor comprising: an insulating substrate including an elongated rectangular surface as viewed in plan, the insulating substrate including a first long side surface, a second long side surface opposite to the first long side surface, a first short side surface, and a second short side surface opposite to the first short side surface; a resistor film formed on an upper surface of the insulating substrate; a pair of upper electrodes formed on the upper surface of the insulating substrate and electrically connected to the resistor film; and a pair of terminal electrodes formed on two long side surfaces of the insulating substrate, each terminal electrode being electrically connected to one of the upper electrodes; wherein: the upper electrodes include a first upper electrode which is an elongated strip adjacent to and extending along the first long side surface of the insulating substrate; the upper electrodes include a second upper electrode which is an elongated strip adjacent to and extending along the second long side surface of the insulating substrate; the resistor film includes a first longitudinal end connected to the first upper electrode; the resistor film includes a second longitudinal end connected to the second upper electrode; and the chip resistor includes a connection position at which the resistor film is connected to the first upper electrode and another connection position at which the resistor film is connected to the second upper electrode, the connection positions being spaced from each other by a predetermined distance in a longitudinal direction of the upper surface of the insulating substrate; the resistor film includes a first connection portion provided at the first longitudinal end for connection to the first upper electrode, and a second connection portion provided at the second longitudinal end for connection to the second upper electrode; the first longitudinal end of the resistor film is connected to the first upper electrode via the first connection portion, and the second longitudinal end of the resistor film is connected to the second upper electrode via the second connection portion.
