Abstract: To provide a conductive member capable of suppressing an increase in contact resistance, and a production method therefor. To solve the problem by providing a conductive member having a Ni plating layer 3 on the surface of contact parts 2 provided on a substrate 1, an arithmetic average roughness Sa of the surface of the Ni plating layer 3 being 20 nm or more. In the Ni plating layer 3, the full width half maximum of a peak at the position of a Ni (200) plane in an x-ray diffraction diagram is preferably 0.6 or less, and an indentation hardness HIT of the Ni plating layer 3 is preferably 5000 n/mm2 or less.

Abstract: Provided are: a method of anchoring Sn powder that allows a Sn coating layer exhibiting excellent adhesion property and excellent heat cycle property to be adhered to and deposited on a surface of an aluminum substrate by means of a cold spray process, which is low in device cost and is high in productivity; and an electrically-conductive aluminum member produced by the method. The method of anchoring Sn powder onto an aluminum substrate is a method of anchoring Sn powder onto a surface of an aluminum substrate including depositing and anchoring Sn powder to form a Sn coating layer on the surface of the aluminum substrate by means of a cold spray process, the method including spraying the Sn powder onto the aluminum substrate under spray conditions of an operating gas temperature of 60° C. or less, an operating gas pressure of 0.30 MPa or more, and a spray distance between a spray gun nozzle and the aluminum substrate of from 5 to 30 mm.
