<p>PROBLEM TO BE SOLVED: To provide an optical coupling element which can suppress noise generated during output from a light reception part by suppressing a displacement current generated between a light emitting element and a light receiving element. SOLUTION: This optical coupling element 1 comprises a light emission part 11, a light reception part 12, and a distance adjusting spacer 13. The light emission part 11 is equipped with a light emitting element 112 fitted to a lead frame 111. The light reception part 12 is equipped with a light receiving element 122 fitted to a lead frame 121. The distance adjusting space 13 is equipped with a metal grating 142 fitted with a connecting terminal 141 connected to the lead frame 121. Those light emission part 11, light reception part 12, and distance adjusting spacer 13 are coupled through the distance adjusting space 13 while the light emitting element 112 and light receiving element 122 face with each other, thereby constituting the optical coupling element 1.</p> |
