Claim:
1. A semiconductor package comprising: a first metal body in which a waveguide structure is formed; a second metal body including a mounting area for a semiconductor device and disposed on the first metal body; a line substrate on which a signal transmission line configured to communicate a waveguide with the semiconductor device mounted on the mounting area; and a lid body made of resin, wherein a structure corresponding to another waveguide structure on an extension of the waveguide structure in the first metal body is formed, an inner wall surface of the structure is metal-coated, and the lid body is disposed at a position facing the first metal body, interposing the second metal body and the line substrate, wherein the waveguide in the lid body is a through-hole, the waveguide in the first metal body is a recessed portion on an extension of the waveguide structure in the lid body to be a back-short end of the waveguide in the lid body, and an inner wall surface of the through-hole is metal-coated.
