Patent ID: 7675755

Claim:
An LED module, comprising: an LED element having a metal film layer for conducting heat from the LED element; said LED element having a metal lead including a heat transfer metal portion, and having an electrode for flip chip mounting the LED element, and a wiring board having at least two metal layers and an electrically insulating layer including a polymer resin and being interposed between each two of the at least two metal layers; wherein a first metal layer of the at least two metal layers on the LED element mounted side of the wiring board has a power supply metal pattern and a heat transfer metal pattern formed electrically insulated from the power supply metal pattern; wherein the power supply metal pattern and the electrode are flip chip connected to each other for enabling electrical conduction, the heat transfer metal pattern and the metal film layer are flip chip connected through an electrically insulating portion interposed therebetween, and the heat transfer metal pattern and the at least two metal layers other than the first metal layer are coupled to each other through a heat transfer portion; and wherein the heat transfer metal pattern and the metal film layer are flip chip connected through both the heat transfer metal portion and an electrically insulating portion interposed between the heat transfer metal portion and the metal film layer.
