Coaxial connector and substrate with coaxial connector

A substrate with a coaxial connector comprising:

• the substrate;
• and the coaxial connector attached to the substrate,
• wherein
• the coaxial connector includes:
• a base surface;
• a coaxial structure where a dielectric is between a central conductor and an outer conductor;
• and
• a protrusion protruding from the base surface,
• wherein
• the central conductor includes a contact portion protruding from the base surface,
• the contact portion is in contact with a conductor pattern formed on a surface of the substrate that is inserted toward the base surface between the contact portion and the protrusion, and
• the outer conductor includes a protruding conductor protruding from the base surface and not in contact with the substrate inserted between the contact portion and the protrusion.
