A moving picture coding method for coding a current block derives a first candidate having a first motion vector predictor derived from a first motion vector that has been used to code a first block. It is determined whether a total number of one or more candidates having the first candidate is less than a maximum candidate number, and a second candidate having a second motion vector predictor is derived when the total number of the one or more candidates having the first candidate is less than the maximum candidate number. The second motion vector predictor is a zero vector. A candidate for coding the current block is selected out of the plurality of candidates having the first candidate and the second candidate.
