ALUMINUM TERMINAL

To provide an aluminum terminal that can suppress the amount of temperature rise when electricity is applied.SOLUTION: An aluminum terminal includes a conductor connection portion that is connected to a conductor, and a plate-like connection portion having a through hole penetrating from a first main surface to a second main surface which are opposed to each other, and a plurality of frustum-shaped convex portions are provided on at least one of the first main surface and the second main surface. The height of the plurality of convex portions is 30 μm or more and 600 μm or less, and the surface roughness of the tips of the plurality of convex portions is 3.0 μm or more and 70.0 μm or less.SELECTED DRAWING: Figure 2 【課題】通電時における温度上昇量を抑制できるアルミニウム端子を提供する。【解決手段】アルミニウム端子は、導線と接続する導線接続部と、対向する第１主面から第２主面まで貫通する貫通穴を有する板状接続部と、を有し、前記第１主面および前記第２主面の少なくとも一方の主面には、錐台状の複数の凸部が設けられ、前記複数の凸部の高さは、３０μｍ以上６００μｍ以下であり、前記複数の凸部における先端部の表面粗さは、３．０μｍ以上７０．０μｍ以下である。【選択図】図２
