Abstract
A package for optical module includes a flat-plate-shaped metal base, and a ceramic circuit board in which a plurality of terminals are arranged in a longitudinal direction, and which is joined to an upper surface of the metal base by soldering. The ceramic circuit board has a shape change portion in which the ceramic circuit board is changed in shape along the longitudinal direction, and a region of the ceramic circuit board not including the shape change portion is joined to the metal base by soldering. The shape change portion of the ceramic circuit board is a portion where a width is changed along the longitudinal direction, or a portion where a thickness is changed along the longitudinal direction.
