<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a light emitting and receiving element having few generations of stresses. <P>SOLUTION: The manufacturing method includes a process for mounting on a substrate a plurality of paired light emitting and receiving elements each pair of which constitute each light emitting and receiving element, a process for sealing the substrate with a light transmitting resin, a process for so removing thereafter each light transmitting resin interposed between each pair of light emitting and receiving elements as to form each recessed portion therebetween, a process for filling each light shading resin into each recessed portion , and a process for dividing it cuttingly thereafter into individual light emitting and receiving elements. Hereupon, the used light shading resin is prepared by kneading a pigment-based absorbent coloring matter with the used light transmitting resin. Concretely, there is used the light shading resin obtained by kneading a carbon black with the light transmitting resin comprising an epoxy resin. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
