Optical cable module and apparatus using the same

An optical cable module comprising:

• a core;
• a clad layer that surrounds the core around the light axis of the core;
• an optical waveguide in which an optical path conversion mirror that converts an optical path of signal light by light reflection on the end face thereof is formed on at least one end portion thereof;
• and
• a light-receiving element that has a fixed positional relationship relative to the end portion of the optical waveguide,
• wherein the optical path conversion mirror reflects light towards a light receiving face of the light-receiving element,
• wherein the optical cable module comprises a first position that is a position in a plane of the light receiving face directly below where light is incident on the optical path conversion mirror after being transmitted through the center of the cross section of the light axis of the core,
• wherein a geometric center of the light-receiving element is disposed at a position offset from the first position, and
• the center of the light-receiving element is placed so as to be made virtually coincident with a spot center of output light when there is a bending in the optical waveguide.
