PROBLEM TO BE SOLVED: To finish a resin sealed section of a resin sealed article consistently in a state free from unevenness by performing resin sealing by uniformly applying a molding resin to a cavity space. SOLUTION: A resin sealing apparatus is equipped with stockers 130A, B which stock granular molding resins 120A, B according to each particle size range, a molding resin supply amount calculation means PC, a molding resin pulling out means to take out the granular molding resins 120A, B based on the supply amount calculated, a loading means 160 for loading the granular molding resins 120A, B, and an injection means for injecting the granular molding resins 120A, B to a lower mold 230 by reciprocating the loading means 160 between a loading position and a mold position, wherein the supply amount calculation means PC conducts a calculation based on the reserved amount of the granular molding resins 120A, B in the stocker 130A, B and the amount of the granular molding resins 120A, B used in the resin sealing of an electronic component 240 so that respective ratios of supply amount of the granular molding resins 120A, B out of stockers 130A, B may become a given ratio.
