1. An electronic element storing package comprising:
a base including a wall body;
a coaxial line located in the wall body; and
a transmission line connected to the coaxial line on a side of the wall body,
wherein
the coaxial line includes a central conductor that is long in one direction, an outer peripheral conductor, and a dielectric that is located between the central conductor and the outer peripheral conductor,
the dielectric has a first end face facing the transmission line,
the wall body includes an opening leading to the first end face,
the opening includes an annular space in contact with the first end face,
an outer diameter of the annular space is larger than an outer diameter of a space located on an opposite side of the first end face in the opening,
the central conductor includes a first section having a first thickness and a second section having a second thickness smaller than the first thickness and located within the dielectric, at least a part of the first section projecting from the first end face,
an end of the first section on an anti-projection side is located between the first end face and a specific position within the dielectric in a longitudinal direction of the central conductor, and
the specific position is a position separated from the first end face toward an inside of the dielectric by ⅛ of an effective wavelength of a transmission signal.
