Moving picture coding method, and the moving picture coding apparatus

The moving picture coding apparatus (100) is spatially adjacent to the coding target block included in the encoding target picture, or the corresponding one or more temporally adjacent the inclusion in different picture from the encoding target picture for each block, in selectively adding a motion vector of a corresponding block in the list, to calculate a second motion vector by scaling a first motion vector of a corresponding block temporally adjacent, first second motion vector is determined whether within the scope of a predetermined size, if the second motion vector is included within the range of a predetermined size, intra adding a second motion vector in the list · comprising inter prediction unit (107).
