1. An optical module on which an optical waveguide chip is mounted and which includes an optical fiber coupled to the optical waveguide chip, the optical module being stored in a package including:
a base on which the optical waveguide chip is mounted, and
a cover, the cover including:
a cover body unit that covers the entire base, and
a cover extension unit having a first surface that that is level with a top surface of the cover body that is opposite to the base and a second surface that is lower than the first surface and higher than the base, the cover extension unit extending out from the top surface of the cover body that is opposite to the base so as to be continuously formed in a direction in which the optical fiber is pulled out from the cover body unit, a gap being formed below the second surface of the cover unit, an adhesive extending from the second surface of the cover extension unit into the gap such that the optical fiber is adhered and fixed to the second surface of the cover extension unit via the adhesive extending from the second surface of the cover extension unit into the gap.
