The invention provides carrier tapes in which, when the carrier tapes are wound up, regardless of the positions of accommodating portions of the upper and lower carrier tapes that overlap each other, electronic components accommodated in the accommodating portions can be reliably secured, so that the electronic components can be prevented from becoming dislodged from the accommodating portions; and electronic-component accommodating members including the carrier tapes.In each carrier tape having the plurality of accommodating portions that accommodate the electronic components and that are formed in a longitudinal direction, a plurality of protrusions are disposed at the bottom surfaces of the accommodating portions, and surfaces of interval portions provided between the accommodating portions that are adjacent to each other are formed lower than surfaces of guides of the carrier tapes.
