LIQUID CARTRIDGE

A liquid cartridge includes a housing (130), a circuit board (64) including an electrode (65), and a liquid supply portion (34) extending from the housing (130) in a depth direction. The housing (130) includes a top wall (39), and first and second protrusions protruding upward from the top wall (39). The first protrusion (43) is positioned rearward but the second protrusion (67) is positioned frontward relative to the circuit board (64). The first protrusion (43) is higher than an upper edge of a front end of the second protrusion (67). No part of the liquid cartridge is positioned higher in a height direction than an imaginary plane (150) in a region between a first point on the first protrusion and a second point on the second protrusion (the upper edge of the front end of the second protrusion) in the depth direction. The imaginary plane (150) passes through the first and second points, and extends perpendicularly to the depth direction.
