A reflective optical sensor (10) includes a cover case (20), which has a window section on the upper surface side for passing light and a storing space (21) at a lower section, and a shield cover (24) for covering an opening of the storing space (21) at the lower section of the cover case (20). In the storing space (21), a circuit board (50), a light receiving element (60), a light blocking plate (62), an electronic circuit (70), a light transmitting substrate (80), a light emitting element (82) and the like are stored and arranged. On the light transmitting substrate (80), the light emitting element (82) is attached at the center portion by using a bump terminal, and the light transmitting substrate is attached to the circuit board (50) at the peripheral section. The light transmitting substrate (80) is arranged on an upper surface side of the light receiving element (60) so that the light emitting element (82) is substantially at the center of the light receiving element (60). |
