Abstract
An optical semiconductor element includes: a semiconductor substrate that is semi-insulating; a columnar body that is formed on a front surface-side of the semiconductor substrate and configured to emit or receive light from the front surface-side; a front surface-side electrode that is connected to the columnar body; a back surface-side electrode formed on a back surface-side of the semiconductor substrate; and an electrically conductive member that is formed to penetrate through the semiconductor substrate to connect the front surface-electrode and the back surface-side electrode, and has a protruding portion protruding on the front surface-side of the semiconductor substrate.
