PROBLEM TO BE SOLVED: To provide a surface mounting type semiconductor light emitting device which can be used for both top light emission and for side light emission and also can enhance the brightness in light emission. SOLUTION: This semiconductor light emitting device is equipped with a mounting board 1 where quartercircular n-electrodes 1a and p-electrodes 1b are made at four corners, an LED5 which is mounted on the mounting board 1, being made electrically contionous to the n-electrode 1a and the p-electrode 1b, and a light reflective case 2 which is joined with the mounting board 1, surrounding the LED5. |
