Provided are a side member from which a clad member for heat exchanger exhibiting excellent productivity and corrosion resistance while preventing poor adhesion can be produced in production of a clad member for heat exchanger by controlling the surface state and flatness, a method for producing the side member, and a method for producing a clad member for a heat exchanger by using the side member. A side member (A) consists of a core material and one or more layers of side member (A) applied onto one side or both sides thereof and being used in a clad member for a heat exchanger, wherein a plurality of periodic forms (B) of fine groove which become arcuate toward one direction of the side member (A) is formed on the surface of the side member (A). The periodic form (B) of fine groove extends up to the outer circumferential edge of the side member (A) with a radius of curvature of 800-1500 mm and has a period (D) of 1-8 mm in the above-mentioned direction of the side member (A) and surface roughness of the side member (A) in the above-mentioned direction of 1-15 μm 10-point average roughness (Rz).

A lighting device 12 of the present invention includes a plurality of light sources 17, a power supply board 30 and a plurality of connectors 40. The power supply board 30 is configured to supply drive power to the light sources 17. The connectors 40 are provided for making electrical connections between the power supply board 30 and the light sources 17. The connectors 40 are arranged such that the adjacent connectors 40 are arranged in staggered layout. Namely, large space is provided between the adjacent connectors 40. This makes mounting work of the connectors easy and reduces electrical discharge between the connectors.
