To provide a stretchable layered sheet for a garment for biological information measurement, the sheet having excellent electroconductivity and stretchability, acquiring electrical signals in a stable manner, having improved adhesiveness to a substrate, and being free of electrode peeling or wire breaking when subjected to the stress and deformation occurring during dressing/undressing and laundering. This stretchable layered sheet is characterized by: being constituted of at least two layers, a stretchable insulating layer and a stretchable conductor layer, both having adhesiveness； and by having a 90 DEG peeling strength between the stretchable insulating layer and stretchable conductor layer of 1.0 N/cm or greater.本發明提供一種生物體資訊量測用衣服用之伸縮性疊層片，具有良好的導電性、伸縮性，取得安定的電訊號之同時，提高對於基材的黏接性，即使面對穿脫、洗滌時的應力、變形亦不會發生電極之剝離、斷線。本發明之伸縮性疊層片由具有黏接性之伸縮性絕緣層與伸縮性導體層之至少2層構成，其特徵在於：伸縮性絕緣層與伸縮性導體層之層間之90度剝離強度為1.0N/cm以上。
