ていることを特徴とするＬＥＤランプ。1. A cap (3) having an illumination window (3a) formed on a front surface thereof and an LED element holding portion (3b) formed on a rear portion thereof, and the LED element holding portion (3b) of the cap (3). A box-shaped LED element (4) attached to the LED element (4) having a conducting plate (6) inside the element body (5), and an illuminating part (2) having an open front surface. In the LED lamp inserted into the socket (1), the left and right inner wall surfaces of the inner space of the socket (1) are formed of a flat spring plate electrically connected to an external connection terminal portion on the outer surface of the socket (1). And a pair of intermediate connection terminals (9), (9) are provided so as to project, and the pair of intermediate connection terminals (9), (9),
(9) is formed such that its tip portions are bent in the shape of substantially inverted eight shapes in the direction of the inner bottom surface of the inner space of the socket (1), and the left and right outer wall surfaces of the LED element (4) have the same element body. (5) A pair of element-side connection terminals (7), (7) made of a flat spring plate integrally continuous with the inner conductive plate (6) are provided so as to project, and the pair of element sides are connected. The connection terminals (7), (7) are formed such that their tip portions are bent in a substantially eight-shape in a direction opposite to the direction of the inner bottom surface of the inner space of the socket (1) into which the connection terminal (7) is inserted. In the state where (2) is inserted into the socket (1), the element-side connection terminals (7) and (7) are inserted into the intermediate connection terminals (9) and (9), and are inserted and slidably elastically polymerized. LED lamp characterized by having.
