Claim 2:
3. A semiconductor package comprising:
the header for the semiconductor package as claimed in claim 1;
a Peltier device arranged on the upper surface of the eyelet and away from the first metal block, at least a portion of the Peltier device being located inside the U shape of the first metal block;
a second metal block arranged on the Peltier device and away from the first metal block, at least a portion of the second metal block being located inside the U shape of the first metal block, the second metal block having a side surface facing a direction that is same as the first end surface and the second end surface; and
a third substrate having a front surface on which a light emitting device is mounted, and a back surface that is an opposite side surface of the front surface of the third substrate, the back surface of the third substrate being fixed to the side surface of the second metal block,
wherein a third portion that is a portion of the back surface of the third substrate is exposed from the second metal block,
wherein a ground pattern is formed on the third portion of the third substrate, and
wherein the ground pattern formed on the first portion of the first substrate, the ground pattern formed on the second portion of the second substrate, and the ground pattern formed on the third portion of the third substrate are electrically connected via a linear member.
