Tray and electronic device

A tray inserted in an electronic device, and housing a card removable from the electronic device, the tray comprising:

• a first interior wall partially defining a housing space housing the card;
• a second interior wall facing the first interior wall, and partially defining the housing space;
• and
• an elastic member provided to the second interior wall, wherein
• the elastic member is formed of rubber, and configured to change in shape in conformity with a shape of the card while the card is housed in the tray, and to apply to the card elastic force toward the first interior wall, wherein
• the tray further comprises a fall-out prevention stopper provided to define a bottom face of the housing space, and configured to prevent the card from falling out,
• in a case where a face facing the bottom face in the housing space is an open face, in a cross-sectional view of the elastic member illustrated on a plane determined by a direction in which the first interior wall and the second interior wall face each other and by a direction perpendicular to the bottom face, at least a portion of the elastic member is formed so that a side of the open face is larger in a thickness of the elastic member than a side of the bottom face.
