<p>PROBLEM TO BE SOLVED: To provide a high-reliability optical printer head which can improve the productivity. SOLUTION: A light emitting element array chip 3 having a plurality of light emitting elements 4 and terminal electrodes 5 on an upper face is loaded on a circuit board 1 having a plurality of circuit wiring lines 2 to be electrically connected to the terminal electrodes 5. Moreover, a housing 7 for holding a lens array 6 above the light emitting element array chip 3 is placed on the circuit board 1. In this optical printer head, a connecting conductor layer 8 for electrically connecting the terminal electrodes 5 and the circuit wiring lines 2 with each other by butting into contact with the terminal electrodes and the circuit wiring lines is applied to an inner face of the housing 7.</p> |
