Method for manufacturing molded product

A method for manufacturing a molded product, comprising:

• a deposition step of depositing a mixture including a fiber and starch in air;
• a humidification step of applying water to the mixture;
• and
• a molding step of heating and pressurizing the mixture applied with water to obtain a molded product, wherein
• the starch has a gelatinized and then pulverized particle diameter d50 of 0.30 mm or more and 1.0 mm or less, which is an average particle diameter of a finely pulverized product determined by a following measuring method comprising:
• adding a predetermined amount of water to the starch to give an aqueous solution of 18 mass %;
• placing 30 g of the aqueous solution in an airtight container and heating the solution at 100° C. for 1 hour to obtain a gelatinized product;
• heating and drying the gelatinized product at 100° C. for 3 hours in an open condition to obtain a solidified product;
• roughly pulverizing the solidified product with a hammer and then removing coarse particles by a sieve with an opening of 3 mm to obtain a roughly pulverized product;
• pulverizing 3 g of the roughly pulverized product using a mixer BM-RT-08 (manufactured by Zojirushi Corporation) for 1 minute to obtain a finely pulverized product, and
• dispersing the finely pulverized product in ethanol and measuring a volume average particle diameter d50 with a particle size distribution measuring apparatus MT-3300EXII (manufactured by MicrotracBEL Corporation).
