<p>One purpose of the present invention is to provide an optical module which can prevent heat generated inside the optical module from heating said module to a high-temperature state. This optical module is provided with a CDR device (50b), a drive IC (50a) which drives a light emitting and receiving element (52), a circuit substrate (24) having a first area (A1) where the CDR device (50b) is mounted and a second area (A2) where the drive IC (50a) is mounted, and a metal housing (28) which houses at least a portion of the circuit substrate (24). The optical module further has a first heat dissipation sheet (56) which is mounted on the surface opposite of the surface where the CDR device (50b) is mounted in the first area (A1), and a second heat dissipation sheet (57) which is mounted on the surface opposite of the surface where the drive IC (50a) is mounted in the second area (A2), wherein at least a portion of the first heat dissipation sheet (56) and the second heat dissipation sheet (57) contact the metal housing (28).</p> |
