Abstract: Discussed are a lamp or a lamp device employing a semiconductor light-emitting element to have a high degree of luminance uniformity. A lamp includes a circuit board; a bus electrode formed along one direction on the circuit board; electrode lines on the circuit board to extend from the bus electrode; semiconductor light-emitting elements arranged in the direction in which the electrode lines are formed, and spaced a predetermined distance apart from a nearby electrode line; transparent electrodes for electrically connecting the semiconductor light-emitting elements to the electrode lines; a current input unit formed along the one direction in parallel to the bus electrode; and connecting electrodes arranged between the bus electrode and the current input unit along the one direction, to electrically connect the bus electrode to the current input unit, wherein a resistance value of certain of the connecting electrodes is different from a resistance value of the rest.
