PROBLEM TO BE SOLVED: To provide an electronic part capable of realizing downsizing by reducing a mounting area, a circuit board on which the electronic parts are mounted, and an illumination fixture using the circuit board. SOLUTION: A parts substrate 20 of the electronic parts 10 is integrally constituted of the upper parts substrate 21, and the lower parts substrate 22, and a projection part 222 to protrude from the upper parts substrate 21 is formed on both front and rear sides of a length direction in the lower parts substrate 22. Then, the end part 223 of a width direction of the projection part 222 is made more inside than the end part 212 of the upper parts substrate 21. Accordingly, when supporting the end part of the width direction of the electronic parts 10 by using an automatic mounting machine 16, the automatic mounting machine 16 is not protruded into at least one of the width directions of the electronic parts 10. Accordingly, there is no need to install a space CS for the mounting machine between the neighboring electronic parts 10, and downsizing can be realized by reducing the mounting area.
