<p>PROBLEM TO BE SOLVED: To provide a photocoupler with dielectric strength improved, without lowering the photo transfer efficiency of a photocoupler. SOLUTION: The distance between a top end 22aa of an input lead frame 22a and a top end 24aa of an output lead frame 24a is held at a fixed value and a distance L11 is provided between the input lead frame 22a and output lead frame 24a which appears on the outside of a light-permeable resin 16.</p> |
