A coaxial cable comprising:
- a core wire;
- a plurality of sheaths that are tubular and made of metal and coaxially cover the core wire;
- a powdered insulating material filled between the core wire and an innermost sheath, and between the plurality of sheaths, respectively;
- a first airtight portion that hermetically seals between the core wire and the innermost sheath;
- and
- a second airtight portion that hermetically seals between an inner sheath and the sheath on an outer side of the inner sheath, wherein
- the second airtight portion includes a first mounting portion made of metal that is hermetically attached to the inner sheath, a second mounting portion made of metal that is hermetically attached to the sheath on the outer side of the inner sheath to which the first mounting portion is attached, and an insulating portion that hermetically connects the first mounting portion and the second mounting portion in an electrically insulated manner.
