<p>PURPOSE:To enable high-quality writing-in to a sensitive-body, by constituting the title head so that light does not arrive at the sensitive-body by penetrating through an optical fiber array base even in a near infrared ray sphere of a light-emission wave length of a light-emission diode array chip. CONSTITUTION:In an optical print head wherein a plurality of optical fibers 12 are built in a part of base glass 11 on the surface of which a plurality of circuit conductor layers 13 are formed by penetrating through in its thickness direction and a plurality of light-emitting elements 15 are arranged on the upper part of a position where an end face of the optical fiber 12 of the base glass 11 is exposed, this is a print head wherein a light absorbing layer 18 is formed on a part which is the rear of of the base glass 11 where the other end face of the optical fiber 12 is exposed and a position on which at least the light-mission element 15 faces is excluded.</p> |
