PROBLEM TO BE SOLVED: To provide an LED bulb that is steadily supported to the power feeding socket at the prescribed position and has a wide irradiation range, and is superior in perceptivity. SOLUTION: This is an LED bulb 1a which comprises a wedge base part 12 that is inserted between terminals T1, T2and T3, T4of plate-spring shape that are provided in the power feeding socket 2 opposed to each other, and in which grooves (lateral grooves) 123, 124 in which the bent portions t1, t4of the terminals T1, T4arranged alternately are engaged are formed respectively at the prescribed part of the front face A and the rear face B of the wedge base part 12 of nearly flat shape that are pinched by the above terminals T1-T4, and further, by providing a lens 13, irradiation range is widened.
