Molding die, resin molding apparatus, and method for producing resin molded product

A molding die used for compression molding, comprising:

• a first die, and
• a second die, wherein
• the first die and the second die are disposed so as to face each other,
• the first die includes a die main surface member constituting a main surface as a bottom surface or an upper surface of a die cavity, and a die side surface member constituting a side surface of the die cavity,
• the die cavity is formed of a space surrounded by the die main surface member and the die side surface member,
• a resin material can be stored in the die cavity,
• the die side surface member is capable of moving up and down relatively to the die main surface member,
• an elastic member is disposed on a side of the die side surface member opposite to a side facing the second die, and
• the elastic member is disposed so that a pressured state along an outer periphery of a planar shape of the die cavity be partially different.
