MEMBER FOR INJECTION MOLDING, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a member for injection molding which suppresses drawing of hydrogen from a molten resin, and suppresses weakening of characteristics of metal.SOLUTION: There is provided a member for injection molding having a contact surface with which a molten resin contacts, where at least a part of a region of the contact surface is formed of metal (A) formed of a predetermined metal element and a hydrogen drawing suppressed substance (B), and a molar ratio of the hydrogen drawing suppressed substance (B) to the metal (A) per 1.5 nmat an arbitrary position of the region is 1/20 to 1/5.SELECTED DRAWING: Figure 1
