The information storing medium has a substrate, a storing element, provided on the substrate, for storing information, a protecting portion, covering the storing element, for protecting the storing element, an electrical contact point that is provided beside the protecting portion on a side of the substrate, on which the storing element is provided, and is electrically connected to the storing element, and a sliding region that is provided on the electrical contact point. In the information storing medium, when the storing medium is mounted on the apparatus main body, the electrical contact point contacts a main body electrical contact point provided on the apparatus main body. Also, when the electrical contact point and the main body electrical contact point contact each other, the main body electrical contact point slides on the electrical contact point in the sliding region.
