Provided is a novel LED flash light source that is lightweight and has a long life, high effective light intensity, small power consumption and excellent impact resistance, and in which the light intensity can be changed. This LED flash light source (10) for a runway embedded-type flash light device comprises an LED module (11), a frame-shaped attachment plate (12), a lens member (13), and an impact-absorbing sheet. The lens member (13) is attached in a hollow section within a frame of the frame-shaped attachment plate (12). The lens member (13) is a lens member (13) that provides a uniform luminance distribution to an emission surface of flash light emitted from each LED (11b). The impact-absorbing sheet includes a lower impact-absorbing sheet (14a) and an upper impact-absorbing sheet (14b). The lower impact-absorbing sheet (14a) is arranged on the LED module (11). The frame-shaped attachment plate (12) to which the lens member (13) has been attached is arranged on the lower impact-absorbing sheet (14a). The upper impact-absorbing sheet (14b) is arranged on the frame-shaped attachment plate (12).
