Cu-Mo SUBSTRATE AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a Cu-Mo substrate (10) comprising a Cu base material (1) containing Cu as the main component, an Mo base material (2) containing Mo as the main component and having first and second major surfaces (2a, 2b) opposite to each other, and a first Sn-Cu alloy layer (3) covering the first major surface (2a) and lateral surfaces (2c, 2d) of the Mo base material (2). The second major surface (2b) of the Mo base material (2) is arranged on at least a part of a major surface (1a) of the Cu base material (1), and the first Sn-Cu alloy layer (3) contains not less than 1% by mass and not more than 13% by mass of Sn.
