PROBLEM TO BE SOLVED: To realize motion compensation prediction highly efficiently without transmitting an encoded vector.SOLUTION: In generating a candidate list, a connection motion information candidate list generating unit 230 selects a decoded prediction block whose motion information including information on a motion vector and information on a reference image is effective from among a plurality of prediction blocks adjacent to a prediction block to be decoded, and makes the motion information of the selected decoded prediction block as a selection candidate, and does not make as the selection candidate the motion information of a specific prediction block in the plurality of prediction blocks adjacent to the prediction block to be decoded on the basis of a division type of the prediction block to be decoded and a position in the decoded block of the prediction block to be decoded. A code string analysis unit 201 decodes information indicating a position in the candidate list. A connection motion information selecting unit 231 selects motion information used for motion compensation prediction of the prediction block to be decoded from the candidate list on the basis of information indicating a position in the decoded candidate list.SELECTED DRAWING: Figure 23
