A light-emitting device package and method of manufacturing the same. The method includes: preparing a package main body comprising a plurality of cavities, wherein a light-emitting device chip is mounted in each of the cavities and a through hole is formed in a bottom of each of the cavities; preparing a fixed mold providing a first surface that blocks the cavity; coupling the package main body to the fixed mold such that an end portion of the cavity contacts the first surface; supplying an encapsulation material into the cavity through the through hole; hardening the encapsulation material; and separating the package main body from the fixed mold, and dicing the package main body into a plurality of light-emitting device packages using a singulation operation. The encapsulation material is supplied while disposing the package main body on the fixed mold so that the encapsulation material is supplied in a gravitational direction.
