Claim 9:
10. A semiconductor device comprising:
a package comprising:
a heat dissipating body comprising a metal,
an insulating part surrounding the heat dissipating body and fixed to an upper surface of the heat dissipating body, the heat dissipating body and the insulating part defining a recess, wherein a lower surface of the recess is the upper surface of the heat dissipating body and a lateral surface of the recess is a lateral surface of the insulating part,
one or more semiconductor laser elements disposed on the heat dissipating body and inside of the recess, and
at least one outer metal layer that is located on a lower surface of the insulating part and is spaced from a lower surface of the heat dissipating body;

a mounting substrate comprising:
at least one first metal pattern located at an upper surface of the mounting substrate, and
a second metal pattern located at the upper surface of the mounting substrate,
wherein the second metal pattern is located inward of the at least one first metal pattern and is spaced from the at least one first metal pattern;

at least one first bonding member located between the at least one outer metal layer and the first metal pattern, wherein the at least one first bonding member comprises a metal material; and
a second bonding member located between the lower surface of the heat dissipating body and the second metal pattern, wherein the second bonding member comprises a metal material.
