Zusammenfassung:	The present invention relates to a mixture film for manufacturing dry electrodes for secondary batteries, a dry electrode containing the same, and a method for manufacturing the same. According to one aspect of the present invention, a film for a mixture electrode is characterized in that unit films for electrodes having a fibrous binder and an active material are laminated in two or more layers, and among the two or more layers of the unit films for electrodes, the machine direction (MD) of the unit films for electrodes facing each other are parallel to each other. 본 발명은 이차전지용 건식 전극의 제조를 위한 합제 필름, 이를 포함하는 건식 전극 및 이의 제조방법에 관한 것이다. 본 발명의 일 측면에 따른 합제 전극용 필름은 섬유화된 바인더 및 활물질을 포함하는 전극용 단위 필름이 2층 이상 적층되어 있고, 상기 2층 이상의 전극용 단위 필름 중 서로 대면하는 전극용 단위 필름의 기계방향(MD)이 서로 평행한 것을 특징으로 한다.
