1. An optical module comprising:
an optical fiber block;
an optical fiber to which the optical fiber block is attached, the optical fiber having a curved portion;
an optical waveguide chip optically connected to the optical fiber; and
a wall structure provided in a vicinity of the optical fiber,
wherein the wall structure is arranged at a location at which, when the optical fiber comes into contact with the wall structure, the wall structure reduces a restoring force of the optical fiber that is applied to an optical connection portion between the optical waveguide chip and the optical fiber block, by a resistance that acts on the optical fiber from the wall structure, and
wherein a cross section of the wall structure is L-shaped and the optical fiber is in contact with two portions that form the cross section being L-shaped.
