Molten glass (G) is set and press-molded in a molding die ( 60 ) having dies ( 621 A 1, 621 A 2 ) corresponding to a lens array. After the molding, the molded article is removed from the molding die ( 60 ) and separated by bending at a bend-separation face ( 121 C), which is a boundary part of adjacent lens arrays, so that two lens arrays are produced.
