    <title>Abstract</title>
    In this study, we focused on the dependence of the AC loss in REBa2Cu3O#D
    <italic>y</italic>
    #DR (REBCO, RE = rare earth, Y, Eu, Gd) superconducting tapes stacked perpendicular to the tape face on the interval between the superconducting layers. The AC loss of the 2-layer stacked tapes with various interval in perpendicular field was investigated by pickup-coil method. The AC loss for external applied magnetic field, <italic>B</italic>
    m, below the penetration field, <italic>B</italic>
    p, increases with increasing the interval. In the case that the ratio of the distance between the neighboring superconducting layer, <italic>D</italic>, to the width of the tape, <italic>w</italic>, (<italic>D</italic>/<italic>w</italic>) is smaller than 0.1, the AC loss of 2-layer tapes decreased to 1/2 of that of 1-layer tape. On the other hand, in the case of <italic>D</italic>/<italic>w</italic> being larger than 0.1, the AC loss of 2-layer tapes was larger than 1/2 and it approached the AC loss of 1-layer tape with increasing <italic>D</italic>/<italic>w</italic>. From the result obtained in this study, it is predicted that, for <italic>B</italic>
    m below <italic>B</italic>
    p, the AC loss of stacked REBCO tapes with large <italic>D</italic>/<italic>w</italic>, such as multifilamentary tapes, is larger than the AC loss of stacked non-scribed REBCO tapes. However, for <italic>B</italic>
    m above <italic>B</italic>
    p: a large AC loss region, it is known that the AC loss of the multifilamentary tapes decreases compared with that of non-scribed tapes. Next step, AC loss of the multifilamentary tapes for <italic>B</italic>
    m below <italic>B</italic>
    p will be investigated experimentally and theoretically.
