Abstract
A circuit substrate includes a first terminal connected to a storage device, a second terminal to which voltage higher than voltage which is applied to the first terminal is applied, and a third terminal. The third terminal is disposed adjacent to the first terminal and the second terminal and connected to an overvoltage detection section provided in a printer. A convex portion is provided on a substrate surface between the first terminal and the second terminal, and a configuration is made such that a liquid droplet easily spreads from the second terminal to the third terminal rather than the liquid droplet spreading from the second terminal to the first terminal.
