A radiator for a transformer is provided to reduce a management cost for maintenance and repair by replacing a damaged radiating plate by the piece. A radiator for a transformer(101) includes a header pipe(103), a plurality of radiating plates(107), a sealing cap(108), and a coupling device. The header pipe is coupled at the upper and lower parts of a transformer body(102), and circulates an insulating oil. The radiating plate includes a radiating unit(104) which has a path for the insulating oil, and a radiating flange(106) which is coupled at the upper and lower ends of the radiating unit, has a through hole(105) in the orthogonal direction of the path, and has greater thickness than the radiating unit. The sealing cap is bolt-coupled at the radiating flange of the last radiating plate among the radiating plates connected to the header pipe, and closes the through hole. The coupling device couples the radiating plates to the header pipe.
