Disclosed is a cartridge for a secondary battery, capable of preventing the inflow of gas, generated from the secondary battery, into a cooling flow passage or a duct connected thereto, by enhancing the sealing strength at a stack portion when a plurality of cartridges are stacked. The cartridge for a secondary battery according to the present invention comprises: upper and lower cooling plates which are formed as a plate shape, and arranged to be spaced at a predetermined interval while facing each other, thereby forming a cooling flow passage in a space therebetween; a main frame which wraps outer circumference portions of the upper and lower cooling plates, has an opening formed in a horizontal direction in at least one lateral surface to expose the cooling flow passage through the opening, has a sealing rib protruding upward and downward above or below an area of formation of the opening, and has a dented portion with a larger size than the sealing rib formed at the opposite side to an area of formation of the sealing rib; and a sealing member of which upper and lower portions are coupled with the sealing rib, wherein when main frames are stacked above and below, a portion of the sealing member is inserted into a dented portion of a neighboring main frame. |
