Abstract

There are provided a power supply device for an optical functional component that supplies power to the optical functional component with reliability for a long term and enables easy exchange of the optical functional component, and an optical functional module having such a power supply device, where the power supply device is provided with a reception electrode 104, a power supply electrode 107-1 that supplies power to the reception electrode 104 while holding tight the reception electrode 104 on its side faces and thereby holding an optical functional component 105-1 detachably, and a protecting member 108 that is made of an insulating material and surrounds the power supply electrode 107-1 to prevent current leaks, and the power supply electrode 107-1 is comprised of two bent metallic members (107-1a and 107-1B) which are in intimate contact with the reception electrode 104 by elasticity.
