NOVELTY - A sugar liquid manufacturing apparatus (110) comprises water-heat-treatment part (210) which hydrothermally treats lignocellulosic biomass and generates 1st solid-liquid mixture, enzyme treatment part (230) which hydrolyzes 1st solid-liquid mixture with enzyme and generates 2nd solid-liquid mixture, 1st pulverization part (240) which pulverizes 2nd solid-liquid mixture that is hydrolyzed by solid acid catalyst which accelerates conversion reaction from polysaccharide to monosaccharide, and solid-acid-catalyst part (250) which generates monosaccharide liquid containing monosaccharide.    USE - A sugar liquid manufacturing apparatus used for manufacturing biomass-derived material (claimed).    ADVANTAGE - Polysaccharide can be hydrolyzed efficiently and time of hydrolysis is shortened.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) manufacture of sugar liquid which involves hydrothermally treating lignocellulosic biomass, generating 1st solid-liquid mixture, hydrolyzing 1st solid-liquid mixture using enzyme, generating 2nd solid-liquid mixture, pulverizing 2nd solid-liquid mixture, hydrolyzing pulverized 2nd solid-liquid mixture by solid acid catalyst which accelerates conversion reaction from polysaccharide to monosaccharide, and generating liquid monosaccharide containing monosaccharide; and    (2) manufacture of biomass-derived material which involves hydrothermally treating lignocellulosic biomass, generating 1st solid-liquid mixture, hydrolyzing 1st solid-liquid mixture using enzyme, generating 2nd solid-liquid mixture, pulverizing 2nd solid-liquid mixture, hydrolyzing pulverized 2nd solid-liquid mixture by solid acid catalyst which accelerates conversion reaction from polysaccharide to monosaccharide, and generating liquid monosaccharide containing monosaccharide.
