Abstract

Disclosed is a flexible printed wiring board (100) which is configured by being provided with a reflecting material layer (6). The reflecting material layer is formed by being provided with an opening (9) that is provided in a predetermined region, and the flexible printed wiring board is configured by being provided with a protection film (10), which is provided with an opening (12) that corresponds to the opening of the reflecting material layer (6), and which is removably laminated on the reflecting surface (6a) of the reflecting material layer.

Description

Technical field [0001] The present invention relates to a printed wiring board, a printed wiring board assembly, a manufacturing method of a printed wiring board, and a lighting device. In detail, it relates to a printed wiring board etc. which does not damage the reflective material layer in a manufacturing process etc., and can improve the light utilization efficiency of an LED light emitting element. Background technique [0002] In recent years, as the efficiency of LED light-emitting elements has increased, the scope of its use has expanded. For example, it is not only used in lighting devices as alternative light sources for incandescent bulbs or halogen bulbs, but also in large-scale lighting devices such as backlights of liquid crystal display devices. [0003] When LEDs are used for lighting, it is desirable to increase the efficiency of elements, and it is desirable to effectively apply light. In order to improve light utilization efficiency, a reflective material layer...
