PROBLEM TO BE SOLVED: To provide a carbon support material for an improved anticorrosive catalyst, which shows activity comparable to that of a conventional catalyst.SOLUTION: A carbon support material consists of a carbon material having a specific surface area (BET) of 100-600 m/g and a micropore area of 10-60 m/g, preferably 25-60 m/g, and having a specific corrosion rate of less than 65%. The carbon support material loses 20% or less of its mass in an accelerated test involving a 1.2 V-potential hold over a 24-hour period at 80°C. A carbon material manufacturing method comprises the step of performing a thermal treatment on a carbon material at a temperature of 800-1100°C for 30 minutes to 4 hours. The method is arranged to decrease the specific corrosion rate of the carbon support material, in which carbon black is processed by at least one kind of gas selected from oxygen, ozone, hydrogen peroxide, nitrogen dioxide, air, carbon dioxide and vapor to manufacture a carbon material having a specific surface area (BET) of 100-600 m/g and a micropore area of 10-60 m/g.SELECTED DRAWING: Figure 1 【課題】従来の触媒に匹敵する活性を示し、耐腐食性である改善された触媒の為のカーボン担体材料の提供【解決手段】カーボン担体材料は、１００〜６００ｍ２／ｇの比表面積（ＢＥＴ）及びし、１０〜６０ｍ２／ｇ好ましくは、２５〜６０ｍ２／ｇの微細孔面積を有し、６５％未満の比腐食率を有し、８０℃で２４時間にわたる１．２Ｖ電位保持を含む加速試験において、質量損失が２０％以下ある、カーボン材料からなるカーボン担体料。カーボン材料が８００〜１１００℃の温度で、３０分〜４時間熱処理するカーボン材料の製造方法。カーボン担体材料の比腐食率を低下させる方法であって、カーボンブラックを、酸素、オゾン、過酸化水素、二酸化窒素、空気、二酸化炭素、及び蒸気から選択される少なくとも１つのガスで処理し、１００〜６００ｍ２／ｇの比表面積（ＢＥＴ）、及び１０〜６０ｍ２／ｇの微細孔面積を有するカーボン材料を製造する。【選択図】図１
