Beschreibung
Zusammenfassung:	Disclosed herein relates to a sealing device for a pouch-type secondary battery, the sealing device including a light source part for irradiating light and a pressurizing part for heating and pressurizing a sealing part of a pouch-type case using light irradiated by the light source part, wherein, by applying a first light transmitting material having a high thermal conductivity and a high light refractive index to the sealing unit of the pressurizing part that contacts the sealing part of the pouch-type case, not only can the sealing part of the pouch-type case be uniformly sealed, but also can prevent damage to the sealing unit heated to a high temperature during sealing, so that the quality of the secondary battery can be improved, and at the same time, processability and economy can be improved.
