Summary:To constitute an optical module (50) in which a comb-shaped submount (20) is fixed on a heat sink (1) and a device (30) having an optical functioning unit is mounted on the comb-shaped submount (20), a stress buffering block (10) that relaxes a thermal stress acting between the heat sink and the comb-shaped submount is placed between the heat sink and the comb-shaped submount (20). With this configuration, a thermal stress acting between the comb-shaped submount (20) and the device (30) mounted thereon is relaxed, and as a result, long-term reliability of bonding parts between the comb-shaped submount (20) and the device (30) is enhanced.
