PROBLEM TO BE SOLVED: To provide an LED print head hardly causing defects in an LED part and capable of easily forming the LED part.SOLUTION: In the LED print head, an LED part (6) includes rod-like first and second light emitting diodes (7A, 7B) which have different electrical connection polarities each other relative to first and second electrodes (11, 12) and are mingled at random while the polarities are not aligned, and a drive circuit (15) drives the first and second light emitting diodes (7A, 7B) with alternating current. When a solution including a plurality of rod-like light emitting diodes (7) are coated on a glass substrate (10) and a voltage is applied between the first and second electrodes (11, 12), a plurality of light emitting diodes 7A, 7B can be electrically connected to the first and second electrodes (11, 12). |
