The present invention provides a new LED flash light source that is light, has a long life, has high effective luminous intensity, can switch the luminous intensity, is low in power dissipation, and is excellent in impact resistance. An LED flash light source (10) for a runway-embedded flash lighting device includes: an LED module (11); a frame-shaped attaching plate (12); a lens member (13); and a shock-absorbing sheet. The lens member (13) is attached to a hollow portion in s frame of the frame-shaped attaching plate (12), the lens member (13) is a lens member (13) that allows an emission surface of flash emitted from the LED (11b) to have a uniform illuminance distribution, the shock-absorbing sheet includes a lower shock-absorbing sheet (14a) and an upper shock-absorbing sheet (14b), the lower shock-absorbing sheet (14a) is placed on the LED module (11), the frame-shaped attaching plate (12) to which the lens member (13) is attached is placed on the lower shock-absorbing sheet (14a), and the upper shock-absorbing sheet (14b) is placed on the frame-shaped attaching plate (12).
