The support portion 41 </ b> A has substantially the same width as the width of the substrate 24, and has a length smaller than the pure interval between the LED packages 301 and 302 at the end portions. Thereby, it becomes possible to attach without interfering with the LED packages 301 and 302 at the end. Further, a through hole 43 for attachment is provided in the center of the support portion 41A.

Since the support portion 41 </ b> A straddles the connection portion 27 of the adjacent substrate 24, two through holes 43 are provided, and the support portion 41 </ b> A can be fastened together with the substrate 24 to the heat radiating chassis 22 by screws 242. it can.
Accordingly, the electric wire holder 40A can be attached even in a narrow space.

The electric wire holding part 42 has a columnar shape having an internal space 45 along the longitudinal direction of the substrate 24, and is partly cut and opened outward (opening 44). The inner space 45 has an inner diameter larger than the outer diameter of the electric wire 252 of the power supply line 25, and the size of the opening 44 is smaller than the outer diameter of the electric wire 252.
Therefore, when the electric wire 252 is pushed into the internal space 45 while expanding the opening 44, the opening 44 becomes smaller than the outer diameter of the electric wire 252 after passing through the electric wire 252, so that the electric wire 252 is held in the internal space 45.

Next, the attaching operation of the lighting apparatus 10A will be described.
First, the fixture body 21 of the LED unit 20 </ b> A is attached to the attached surface 11. At this time, when connecting a plurality of LED units 20A in a straight line, a plurality of appliance bodies 21 are connected in a straight line.

  Next, the substrate 24 is attached to the heat dissipation chassis 22 attached to the base 215 of the instrument body 21. At this time, in the connection portion 27, the electric wire holder 40 </ b> A is brought into contact with the surface 241 of the substrate 24, and the screw 242 is passed through the through hole 43 of the electric wire holder 40 </ b> A and the through hole (not shown) of the substrate 24. To conclude.

Thereafter, one of the receiving sockets 251 of the power supply line 25 is connected to the socket 26 of the substrate 24, the electric wire 252 is pushed into the electric wire holding portion 42 of the electric wire holder 40A, and the other receiving socket 251 is inserted into the socket 26 of the adjacent substrate 24.
