Abstract
An information medium includes: a tape reel around which a magnetic tape is wound; a case body that encloses the tape reel; a lid, including a support plate that is pivotally attached to the case body, that opens and closes a withdrawal opening; and a coil spring disposed between the case body and the lid in a state where a first arm portion of the coil spring engages a top plate of the case body and a second arm portion of the coil spring has engaged the lid, the coil spring energizing the lid in a direction of pivotal movement so as to close the withdrawal opening. The coil spring is formed so that the first arm portion is linear, and when the coil spring has been disposed, an end of the first arm portion protrudes from a withdrawal opening-side edge of the top plate.
