Liquid discharge apparatus and storage device

A storage device comprising:

• a first storage section that stores an object in a space between a first surface and a second surface facing the first surface;
• a second storage section that stores an object in a space between a third surface and a fourth surface facing the third surface;
• a first flexible printed substrate for detecting a remaining amount of the object in the first storage section;
• and
• a second flexible printed substrate for detecting a remaining amount of the object in the second storage section, wherein
• the first flexible printed substrate includes
• a first wiring portion including a first electrode provided on the first surface, and
• a second wiring portion including a second electrode provided on the second surface,
• the second flexible printed substrate includes
• a third wiring portion including a third electrode provided on the third surface, and
• a fourth wiring portion including a fourth electrode provided on the fourth surface,
• the first storage section and the second storage section are disposed side by side such that the second surface is located between the first surface and the third surface,
• the second wiring portion has a first shield electrode that is located between the second electrode and the third wiring portion for shielding the second electrode, and
• the third wiring portion does not have a shield electrode for shielding the third electrode between the third electrode and the second wiring portion.
