PROBLEM TO BE SOLVED: To provide a transistor having an annular gate electrode, which includes a connection pad connectable to a secondary gate electrode without severely influencing the transistor characteristics. SOLUTION: The transistor having an annular gate electrode includes the connection pad for the secondary gate electrode where a part of the annular gate electrode extends onto at least one of a source electrode and a drain electrode while interposing an insulating layer between the source electrode and the drain electrode.
