PROBLEM TO BE SOLVED: To provide a die for injection molding and a die for die casting which have excellent temperature controllability and can be produced inexpensively in a short period of time, and a method for using the die for injection molding by which highly accurate molding can be molded. SOLUTION: The dies 1 for injection molding includes: a fixed-side die 2 formed by working, laminating and joining a plurality of metal plates 10; a movable-side die 4 formed by working, laminating and joining a plurality of metal plates 13; and flow passages 3, 5 which cause fluid for adjusting the temperature of the die to flow therethrough, are formed by working, laminating and joining the metal plates 10, 13 and disposed in at least either the fixed-side die 2 or the movable-side die 4.
