An LED leadframe or LED substrate includes a main body portion having a mounting surface for mounting an LED element thereover. A reflection metal layer serving as a reflection layer for reflecting light from the LED element is disposed over the mounting surface of the main body portion. The reflection metal layer comprises an alloy of platinum and silver or an alloy of gold and silver. The reflection metal layer efficiently reflects light emitted from the LED element and suppresses corrosion due to the presence of a gas, thereby capable of maintaining reflection characteristics of light from the LED element.
