Optical module

An optical module which optically connects an optical element with an optical fiber, the optical module comprising:

• a first optical block;
• and
• a second optical block which is assembled with the first optical block, wherein
• the first optical block is an optical block which is to be mounted on a substrate on which the optical element is mounted,
• the second optical block is an optical block configured to hold the optical fiber,
• the first optical block includes
• a base part, and
• two extending parts which extend from the base part in a first direction which is orthogonal to an assembling direction, the assembling direction being a direction in which the second optical block is assembled with the first optical block,
• the second optical block is configured to be accommodated between the two extending parts and to be moved in the first direction between the two extending parts,
• positioning parts are formed on the second optical block, the positioning parts being for positioning the second optical block with respect to the first optical block in each of the assembling direction and a second direction, and the second direction being orthogonal to the assembling direction and being orthogonal to the first direction,
• an extending direction of the optical fiber held by the second optical block is the first direction, and
• a light traveling direction between the base part and the second optical block is the first direction.
