| 1. A light emitting device comprising:
a planar base substrate made of a metal;
an insulating member disposed on a main surface of the planar base substrate;
a conductive member disposed on the insulating member; and
a package member bonded to the insulating member and the conductive member with the insulating member and the conductive member
being disposed at least partially between the base substrate and the package member,
the package member has a plurality of opening portions where the insulating member and the conductive member are exposed at
bottom parts thereof, the opening portions including
a first opening portion in which a light emitting element is mounted, and
a second opening portion located separate from the first opening portion and also opens to a side surface of the package member
with the conductive member being exposed to outside so that an electric connection to the light emitting element is established
when an external electrode is connected to the conductive member in the second opening portion.
