An optical device according to the present invention includes a device substrate, a translucent member, an optical element chip and a conductive portion. On a surface of the device substrate, an opening is provided so as to extend substantially in the vertical direction with respect to a surface of the device substrate and pass through the device substrate, the translucent member is provided so as to cover a first opening mouth of the opening, and the optical element chip is provided so as to cover the other opening mouth thereof. Part of the conductive portion is buried in the device substrate. The outline of the first opening mouth has a point-asymmetrical shape with respect to an approximate center point of the first opening mouth. |
