An electrical connecting terminal used to connect a driving board with a lamp holder of an LED lamp has a base, an elastic sheet, and a plug pin (or a weld pin). A side of the base extends upwards and obliquely and is curved to form the elastic sheet adapted for electrical connection of an electrode of the lamp holder. The side of the base extends outward or is bent to form the plug pin or the weld pin adapted for electrical connection of the driving board. The structure and connecting procedure are simple, the assembly efficiency is high, the connection is stable, and the yield is increased greatly.
