Abstract
An optical subassembly includes: a support block made of ceramic in front of the first surface, the support block having a substrate mounting surface, the support block having a first side opposite to a surface in front of the first surface; an element-mounted substrate on the substrate mounting surface, the element-mounted substrate having a first conductor pattern; a pedestal made of metal and configured to be the same potential as the eyelet, the pedestal situated in front of the first surface; and a lead pin in the through-hole and for transmitting the electric signal. The support block has a metallization pattern that is electrically connected to the pedestal and is continuous from at least a part of the substrate mounting surface to at least a part of the first side.
