인공 피혁 기재와 인공 피혁 기재의 적어도 일면에 적층된 수지층을 포함하는 은부조 인공 피혁으로서, 인공 피혁 기재는, 극세 섬유의 섬유 낙합체와, 3 ∼ 50 질량％ 의 제 1 고분자 탄성체와, 인 원자 환산으로 2.5 ∼ 6 질량％ 의 평균 입자경 1 ∼ 10 ㎛ 의 제 1 인계 난연제 입자와, 1 ∼ 6 질량％ 의 가소제를 함유하고, 수지층은, 제 2 고분자 탄성체와, 인 원자 환산 또는 수산기 환산의 총 함유율로 0 ∼ 8 질량％ 의, 제 2 인계 난연제 입자 및 제 1 금속 수산화물 입자로 이루어지는 군에서 선택되는 적어도 1 종의 평균 입자경 1 ∼ 10 ㎛ 의 난연제 입자를 함유하는 은부조 인공 피혁. Disclosed is a grain-finished artificial leather including: an artificial leather base material; and a resin layer stacked on at least one surface of the artificial leather base material, wherein the artificial leather base material contains: a fiber-entangled body of ultrafine fibers; 3 to 50 mass% of a first elastic polymer; 2.5 to 6 mass%, in terms of phosphorus atoms, of first phosphorous-based flame retardant particles having an average particle size of 1 to 10 µm; and 1 to 6 mass% of a plasticizer, and the resin layer contains: a second elastic polymer; and a total content, in terms of phosphorus atoms or in terms of hydroxyl groups, of 0 to 8 mass% of flame retardant particles having an average particle size of 1 to 10 µm and being at least one selected from the group consisting of second phosphorous-based flame retardant particles and first metal hydroxide particles.
