Provided are a blood collecting puncture device having high safety which can hygienically maintain the inside of a magazine and prevent infection, and the magazine. A blood collecting puncture device has a blood collecting puncture device body removably incorporating a magazine for housing lancets for puncturing human skin. The blood collecting puncture device body has a first housing section for housing not-yet-used lancets and a second housing section for housing used lancets to be disposed of. When a rotor is rotated, individual lancets are sequentially conveyed on a one-by-one basis to a stock position, a puncture position, and a disposal position, and this causes a not-yet-used lancet to be housed in the first housing section and also causes a used lancet to be housed in the second housing section, so that the lancets are separately housed in spaces isolated from each other.
