Summary:PURPOSE: To provide a biaxial actuator wherein the connection pin of a coil bobbin is easily soldered to the power supply land part of a lends holder by a small amount of solder. CONSTITUTION: A biaxial actuator is constructed in such a manner that a lens holder 11 for supporting an objective lens is supported on a fixing part 14 via elastic supporting members 13a, 13b, 13c and 13d, and a focusing coil 126 wound around a vertical axis of a coil bobbin 12 provided in this lens holder and a tracking coil wound on a horizontal axis are provided. A power supply land part 11d provided in the lens holder so as to bring a connecting pin 12d protruding sideways from the coil bobbin 12 into contact therewith is made small in its surface.
