Disclosed are a carbon-based support capable of improving catalytic activity as much as that of a porous support while having excellent durability characteristic to a solid-type support, a catalyst including the carbon-based support, a membrane-electrode assembly including the carbon-based support, and a method for manufacturing the carbon-based support. The carbon-based support for a fuel cell catalyst of the present invention is a solid-type support, and has an outer surface area of 100 to 450 m2/g, a mesopore volume of 0.25 to 0.65 cm3/g, and a micropore volume of 0.01 to 0.05 cm3/g. 公开了一种碳类载体、包括该碳类载体的催化剂、包括该碳类载体的膜-电极组件以及该碳类载体的制造方法，该碳类载体能够在具有固体型载体特有的优异耐久性的同时提高催化活性与多孔型载体同样多。本发明的用于燃料电池催化剂的碳类载体是固体类型载体，并且具有100至450m2/g的外表面积、0.25至0.65cm3/g的中孔体积和0.01至0.05cm3/g的微孔体积。
