Abstract: An optical module includes: a flexible board having a first surface on which a component is mounted and a second surface opposite to the first surface; a bottom electrode part having a bottom surface on which a heat release electrode is provided, the bottom electrode part mounted on the first surface of the flexible board; and a heat release member configured to absorb heat from the bottom electrode part and release the heat to outside. The heat release member is arranged close to said second surface of the flexible board at a position where the bottom electrode part is mounted.
