Zusammenfassung:	A disclosed electron emission source according to the present invention includes an emitter part for emitting electrons for generating X-rays, a guider part for guiding the installation of the emitter part, and a gate part for extracting the electrons emitted from the emitter part. The emitter part is inserted into the guider part to fix its posture, and has a surface which has a non-planar shape and emits the electrons. According to this configuration, it is advantageous to induce the growth of carbon nanotubes in the non-planar region of the emitter part, thereby contributing to the improvement of electron emission efficiency. 개시된 본 발명에 의한 전자방출 소스는, 엑스레이 발생을 위한 전자를 방출하는 에미터부, 에미터부의 설치를 가이드하는 가이더부 및, 에미터부로부터 방출되는 전자를 추출하는 게이트부를 포함하며, 에미터부는 가이더부에 삽입되어 자세 고정되되, 전자가 방출되는 면이 비 평면 형상을 가진다. 이러한 구성에 의하면 에미터부의 비 평면 영역에서의 탄소나노튜브의 성장 유도에 유리하여, 전자 방출 효율 향상에 기여할 수 있다.
