A tape cartridge includes a case having a first through-hole and a second through-hole in the bottom of a first container, a reel disposed within the case and having a cylindrical hub portion with a bottom, a tape wound around the hub portion such that the tape can be fed out, and a reel lock mechanism that allows the reel to be immovably supported. The reel lock mechanism includes an interposing member that can move vertically in the thickness direction of the case, and a support member. The support member includes a first pedestal portion that, in a state in which the reel has been put in contact with the second container and the interposing member has been put in contact with the reel, is positioned immediately below the interposing member and thus immovably supports the interposing member; and an operating portion that is disposed in the first through-hole and allows, with a predetermined operation, support of the interposing member and release of support of the interposing member.
