A forming device includes: a first cavity portion in which a pipe portion is formed and a second cavity portion in which a flange portion is formed, the first cavity portion and the second cavity portion being formed between a first die and a second die; a flange adjusting member which is capable of being advanced into the second cavity portion and is capable of being retreated from the second cavity portion, and which adjusts a length of the flange portion; and a control unit. The control unit sequentially performs a first control of allowing the flange adjusting member to be advanced into the second cavity portion, a second control of allowing the gas supply unit to supply a gas so as to temporarily form the flange portion, and a third control of allowing the flange adjusting member to be retreated from the second cavity portion.

A forming apparatus that forms a metal pipe includes: a heating unit which heats a metal pipe material; a gas supply unit which supplies gas into a heated metal pipe material, thereby expanding the metal pipe material; a die which forms the metal pipe by bringing the expanded metal pipe material into contact with the die; a cooling unit which cools the metal pipe after the forming by a cooling medium; and a control unit which controls an operation of the die, the gas supply unit, and the cooling unit, wherein the control unit makes cooling of the metal pipe by the cooling medium be performed, by controlling an operation of the die such that the die is opened and controlling the cooling unit such that the cooling unit brings the cooling medium into contact with the metal pipe, subsequently to completion of forming by the die.
