A combination motion information candidate list construction unit (162) generates a combination motion information candidate list that is a list of combination motion information candidates using spatial combination motion information candidates and temporal combination motion information candidates. A second combination motion information candidate replenishment unit (165) generates a new combination motion information candidate that, when a reference index shows an available reference picture, includes this reference index, and when the reference index does not show the available reference picture, includes a predetermined reference index, together with a motion vector having a preset size and direction, and adds the new combination motion information candidate to the combination motion information candidate list. A combination motion information selection unit (141) selects one combination motion information candidate from the combination motion information candidate list to which the new combination motion information candidate is added, and derives the selected one combination motion information candidate as motion information relating to a prediction block to be coded.
