To provide a collector feeding device capable of stably feeding a collector into a chamber without generating a natural vibration to the collector.SOLUTION: A collector feeding device 800 that transports a band-like collector 31B toward an electrode formation part forming an electrode by forming an active material 32c layer by coating one surface of the band-like collector 31B with a powder-like active material 32c comprises: a transportation device 200 that transports the band-like collector 31B into a chamber 100 where an inner part is compressed by an atmospheric pressure while the electrode formation part is housed into the inner part via a first slit 110 provided to the chamber 100; and a first tension holding part that is arranged on a front side in a transportation direction of the band-like collector 31B to the chamber 100 and applies a tension in cooperation with the transportation device 200 to the band-like collector 31B.SELECTED DRAWING: Figure 3 【課題】集電体に固有振動などを発生させず、安定してチャンバ内に集電体を供給することができる集電体供給装置を提供する。【解決手段】粉体状の活物質３２ｃを帯状の集電体３１Ｂの一方の面に塗布して活物質３２ｃ層を形成することにより電極を形成する電極形成部に向けて、帯状の集電体３１Ｂを搬送する集電体供給装置８００であって、内部に電極形成部を収容すると共に内部が大気圧よりも減圧されるチャンバ１００内に、チャンバ１００に設けられた第１スリット１１０を介して帯状の集電体３１Ｂを搬送する搬送装置２００と、チャンバ１００に対して帯状の集電体３１Ｂの搬送方向の手前側に配置され、帯状の集電体３１Ｂに対して、搬送装置２００と協業してテンションを付加する第１テンション保持部と、を備えている。【選択図】図３
