The invention provides an output terminal front lead-out type capacitor shell comprising a rear wall plate, an upper wall plate, a lower wall plate, side wall plates and fixing bases. The rear wall plate vertically protrudes along a longitudinal direction so that multiple division parts are formed, and element arrangement space used for arrangement of capacitor elements is formed through division. The upper wall plate is vertically formed forwardly from the upper end of the rear wall plate. The lower wall plate is forwardly formed from the lower end of the rear wall plate in a way of being parallel to the upper wall plate. The side wall plates are combined with the two side ends of the rear wall plate, the upper wall plate and the lower wall plate so that the element arrangement space H with a front open part F is formed. There are at least two fixing bases which are formed in a way of being parallel to the lower wall plate and exposed out of the external side and are provided with fixing slots which are vertically through. A capacitor output terminal M is exposed via the front open part F. Epoxy resin is put in via the front open part F. Epoxy resin injection molding of the capacitor elements and first and second bus bar forming parts is performed.
