## Abstract

The present invention provides a contact with low impedance even in a high frequency band. The contact (1) includes a base part (3), a contact part (5), and a spring part (7). The spring part (7) is elastically deformed to bias the contact part (5) in the x-axis positive direction and the z-axis positive direction. The contact part (5) includes a sliding part (23A) oriented in the x-axis positive direction. The base part (3) includes a part to be slided (14) oriented in the x-axis negative direction. The contact part (5) is biased in the x-axis positive direction by the spring part (7), so that the sliding part (23A) is in pressure contact with the part to be slided (14). The contact part (5) is configured to be slidable in the z-axis direction relative to the base part (3) while maintaining a state in which the sliding part (23A) is in pressure contact with the part to be slided (14).
