PURPOSE: A light emitting device package is provided to increase a heat sink function and a radiation function by exposing a radiating unit consecutively formed with a lead frame to the outside of a body. CONSTITUTION: A body(110) includes a cavity. A first frame(140) and a second lead frame(150) are mounted on the body. An optical source unit(130) is electrically connected to a first lead frame and the second lead frame. A radiation unit(160) is projected to the outside of the body. A floor side of the body includes a depression part(120). The radiation unit is accepted into the depression part.
