LIGHT EMITTING ELEMENT MODULE SUBSTRATE, LIGHT EMITTING ELEMENT MODULE, AND ILLUMINATING DEVICE

摘要

According to an aspect of the invention, there is provided a light emitting element module substrate including: a laminated plate; and a metal layer. The laminated plate includes a base metal plate and an insulating layer provided on the base metal plate. The metal layer is provided on the insulating layer. The metal layer includes a mounting section on which a light emitting element is to be mounted, and a bonding section to which a wiring electrically connected to the light emitting element is to be bonded. The metal layer includes a silver layer which is an uppermost layer of at least one of the mounting section and the bonding section and is formed by electrolytic plating. The mounting section and the bonding section are electrically isolated from a periphery of the laminated plate.
