PROBLEM TO BE SOLVED: To provide a high-frequency package excellent in matching characteristics. SOLUTION: The high-frequency package is equipped with a base plate 11, a dielectric frame 12 surrounding a part of a space on the base plate 11, and a high-frequency transmission line equipped with a first section S1 which is located on the outer side of the dielectric frame 12 penetrating into the inside of the dielectric frame 12 from the outside, a second section S2 which penetrates through the dielectric frame 12, and a third section S3 which is located on the inner side of the dielectric frame 12. The high-frequency transmission line in the first section S1 is composed of a first line S11 which is constant in width, and has a prescribed length and a second line part S12 which is smaller in width and length than the first line part S11, kept constant in width, and has a prescribed length.
