## Abstract

A 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. The central conductor includes a contact portion protruding from the base surface. In response to a substrate being inserted toward the base surface between the contact portion and the protrusion, the contact portion comes into contact with a conductor pattern formed on a surface of the substrate. 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.

## Claims

### Claim 1

A coaxial connector comprising:
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 substrate has an outer edge portion where the conductor pattern is not formed, and
when viewed in a direction normal to the substrate in a state where the substrate is between the contact portion and the protrusion, the protruding conductor protrudes from the base surface in such a manner that the protruding conductor overlaps the outer edge portion.

### Claim 5 (depends on 2)

The coaxial connector as claimed in claim 2,
wherein
the substrate has an outer edge portion where the conductor pattern is not formed, and
when viewed in a direction normal to the substrate in a state where the substrate is between the contact portion and the protrusion, the protruding conductor protrudes from the base surface in such a manner that the protruding conductor overlaps the outer edge portion.
