The present invention relates to a molding device of a composite material structure using an electromagnet, and a molding method of the composite material structure using the molding device. An objective of the present invention is to provide the molding device of the composite material structure using the electromagnet. The molding device is capable of molding a composite material even in a limited space instead of an autoclave requiring a large space for installation, reduces installation costs, and improves safety of installation environment. The molding device of the present invention comprises: a magnetism transmission mold on which a bottom portion of a prepreg-stacked composite material structure is seated, and which transmits a magnetic force to a top portion of the composite material structure; an electromagnet which is attached to a bottom portion of the magnetism transmission mold, and which applies the magnetic force to the magnetism transmission mold; and a magnetism material mixture which contains magnetism materials enabling the magnetic force and attractive force transmitted from the magnetism transmission mold to be generated from the top portion of the composite material structure, and which evenly disperses the attractive force onto the surface of the composite material structure to apply a uniform pressure onto the surface of the composite material structure. 전자석을 이용한 복합소재 구조물 성형장치 및 상기 복합소재 구조물 성형장치를 이용한 복합소재 성형방법에서, 상기 복합소재 구조물 성형장치는 프리프레그를 적층한 복합소재 구조물의 하부가 안착되고 상기 복합소재 구조물 및 상부에 자력을 전달하는 자성전달 몰드와, 상기 자성전달 몰드의 하부에 부착되며 상기 자성전달 몰드에 자력을 인가하는 전자석과, 상기 복합소재 구조물의 상부에서 자성물질을 함유하여 상기 자성전달 몰드로부터 전달되는 자력과 인력을 작용하며 상기 복합소재 구조물의 표면에 상기 인력을 고르게 분산시켜 상기 표면에 균일한 압력을 가하는 자성물질 혼합물을 포함한다.
