A method for granulating a polyamide, comprising the steps of: melting polyamide, whose melt viscosity at glass transition temperature + 160°C and a shear rate of 100s -1 is 3Pa·s to 200Pa·s and whose terminal amino group concentration is 5μeq/g to 70μeq/g, by heating to a range of glass transition temperature + 160°C to glass transition temperature + 180°C; and dropping the resultant in the molten state in granular forms onto a metal belt for solidification to obtain granules, wherein polyamide is polyamide which comprises a diamine unit containing an aromatic diamine unit represented by General Formula (I-1) below or an alicyclic diamine unit represented by General Formula below for 70mol% or more, and a dicarboxylic acid unit containing at least one of a linear aliphatic dicarboxylic acid unit represented by General Formula (II-1) below and an aromatic dicarboxylic acid unit represented by General Formula (II-2) below for a total of 50mol% or more: wherein, in Formula (II-1), n represents an integer of 2-18, and in Formula (II-2), Ar represents an arylene group; and wherein the melt viscosity is determined using a capillograph, a 1 mmφ x 10 mmH die, and the polyamide with a moisture content -adjusted to 500 ppm ± 50 ppm, while the fall-rate of the piston is set to 10 mm/min; the glass transition temperature is determined using a differential scanning calorimeter in which the temperature of the polyamide is elevated to 10°C-260°C at a temperature elevation rate of 10°C/min in a nitrogen gas flow, rapidly cooled with dry ice, and again elevated to 10°C-260°C at a temperature elevation rate of 10°C/min in a nitrogen gas flow, the resultant is stored for 5 minutes once the temperature has reached 260°C, and the temperature is lowered to 120°C at -5°C/min, to thereby obtain the sample on which differential scanning calorimetry measurement is performed to determine the glass transition temperature; and the terminal amino group concentration is determined by weighing 0.5g of polyamide, dissolving it in 30 mL of a mixed solution of phenol/ethanol at a volume ratio of 4/1 at 20-30°C, washing the inner wall of the container once the polyamide is completely dissolved with 5 mL of methanol and then performing neutralization titration using a 0.01mol/L aqueous hydrochloric acid solution to calculate the terminal amino group concentration. melting polyamide, whose melt viscosity at glass transition temperature + 160°C and a shear rate of 100s -1 is 3Pa·s to 200Pa·s and whose terminal amino group concentration is 5μeq/g to 70μeq/g, by heating to a range of glass transition temperature + 160°C to glass transition temperature + 180°C; and dropping the resultant in the molten state in granular forms onto a metal belt for solidification to obtain granules, wherein polyamide is polyamide which comprises a diamine unit containing an aromatic diamine unit represented by General Formula (I-1) below or an alicyclic diamine unit represented by General Formula below for 70mol% or more, and a dicarboxylic acid unit containing at least one of a linear aliphatic dicarboxylic acid unit represented by General Formula (II-1) below and an aromatic dicarboxylic acid unit represented by General Formula (II-2) below for a total of 50mol% or more: wherein, in Formula (II-1), n represents an integer of 2-18, and in Formula (II-2), Ar represents an arylene group; and wherein the melt viscosity is determined using a capillograph, a 1 mmφ x 10 mmH die, and the polyamide with a moisture content -adjusted to 500 ppm ± 50 ppm, while the fall-rate of the piston is set to 10 mm/min; the glass transition temperature is determined using a differential scanning calorimeter in which the temperature of the polyamide is elevated to 10°C-260°C at a temperature elevation rate of 10°C/min in a nitrogen gas flow, rapidly cooled with dry ice, and again elevated to 10°C-260°C at a temperature elevation rate of 10°C/min in a nitrogen gas flow, the resultant is stored for 5 minutes once the temperature has reached 260°C, and the temperature is lowered to 120°C at -5°C/min, to thereby obtain the sample on which differential scanning calorimetry measurement is performed to determine the glass transition temperature; and the terminal amino group concentration is determined by weighing 0.5g of polyamide, dissolving it in 30 mL of a mixed solution of phenol/ethanol at a volume ratio of 4/1 at 20-30°C, washing the inner wall of the container once the polyamide is completely dissolved with 5 mL of methanol and then performing neutralization titration using a 0.01mol/L aqueous hydrochloric acid solution to calculate the terminal amino group concentration.
