A puncturing apparatus includes a housing having a first case and a second case, the housing configured to move at least one of the first case and the second case so that the cases are in an overlapping state in which the first case and the second case overlap one another or a non-overlapping state. A puncturer is housed in the housing and a puncture starting mechanism, having a puncturing button, is configured to activate the puncturer. A first safety section is configured to prevent at least one of the puncturing opening and the puncturing button from being exposed, by placing the first case and the second case in the overlapping state, and a second safety section is configured to disable operation of the puncture starting mechanism in the non-overlapping state of the first case and the second case.
