PURPOSE:To miniaturize an LED printer head by providing a light absorbing members between light emitting diodes on a monolithic light emitting diode array chip composing a light emitting diode array. CONSTITUTION:An LED array chip 605-m is a monolithic LED array in end face luminous type LEDs 701-1, 701-2... are arranged in one row and the P-N junction faces of the LEDs parallel with the adhesion surface between the LED array chip 605-m and a wire substrate 603. A coating is done covering at least the side of the LED with a light absorbing member 2201. |
