An LED module comprises: an LED element having an electrode for flip chip mounting; 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 metal layers; and a metal film layer of the LED element for conducting heat from the LED element. A first metal layer of the at least two metal layers has a power supply metal pattern and a heat transfer metal pattern that are formed electrically insulated from each other. The power supply metal pattern and the electrode are connected to each other; the heat transfer metal pattern and the metal film layer are connected through an electrically insulating portion interposed therebetween; and the heat transfer metal pattern and the metal layers other than the first metal layer are coupled to each other through a heat transfer portion.
