A high voltage transformer having radiation ribs has a laminated core formed of a plurality of accumulated iron plates, first and second windings wound in the laminated core for converting an input voltage to a predetermined output voltage, and a plurality of radiation ribs formed in the accumulated direction of the plurality of iron plates on the outer periphery of the laminated core. The plurality of radiation ribs are formed as the plurality of iron plates are accumulated, by the accumulation of a plurality of protrusion portions formed along each of the plurality of iron plates. Since the radiation ribs are formed on the outer periphery and in the accumulated direction of the laminated core, all the iron plates constituting the laminated core have the same shape and are disposed in the same direction.
