An electrical connecting apparatus is provided to implement stable electric connection and improve position precision of a tip by having a dimension from the tip of a contact to a probe land of 1.1~1.3mm. An electrical connecting apparatus(10) includes a support member(20), a wiring substrate(22), an electric connector(24), a probe substrate(26), a base ring(28), and a fixed ring(30). The support member is a flat plate when viewed from a front surface. The wiring substrate is formed at a lower surface of the support member in a circular flat plate. The electric connector is formed at a lower surface of the wiring substrate in a flat plate. The probe substrate is formed at a lower surface of the electric connector in a flat plate. The base ring includes a rectangular or circular central opening(28a) capable of receiving the electric connector. The fixed ring inserts an edge of the central opening into an edge around the probe substrate.
