The present invention provides an optical module capable of being readily dismounted
from a host board while solving the problem discussed in the specification. An
optical module 10 according to the present invention is an optical module
10 to be inset into a host board 40, which comprises a projection
15 formed in a housing 14 and adapted to engage with a hook 41
provided in the host board 40, and a lever 20 pivotably mounted
on the housing 14 in order to disengage the hook 41 engaging with
the projection 15 to release the engagement, wherein the lever 20 has
a first portion 21A adapted to move with exertion of a force in a direction
toward the housing 14, and a second portion 21B being adjacent to
the projection 15 and adapted to move according to the movement of the first
portion 21A. In this arrangement, as the first portion 21A moves
with exertion of the force on the first portion 21A, the second portion
21B moves in an upheaving direction of the projection 15 to release
the engagement between the hook 41 and the projection 15.
