Claim 0:
1. A liquid cartridge comprising:
a housing defining a liquid storage chamber therein;
a circuit board including an electrode; and
a liquid supply portion provided at the housing and defining therein a liquid passage extending frontward from the liquid storage chamber in a depth direction crossing a gravitational direction,
wherein the housing comprises:
a plurality of walls defining an outline of the liquid cartridge when viewed in a width direction crossing the gravitational direction and the depth direction, the plurality of walls comprising a top wall at which the circuit board is provided;
a first protrusion positioned rearward of the circuit board in the depth direction, the first protrusion protruding upward from the top wall;
a second protrusion positioned frontward of the circuit board in the depth direction, the second protrusion protruding upward from the top wall; and
a third protrusion positioned frontward of the circuit board and rearward of the second protrusion in the depth direction, the third protrusion protruding upward from the top wall,

wherein, when viewed in the width direction, the outline of the liquid cartridge is positioned lower than an imaginary line in a region in the depth direction between a first point defined on the outline of the first protrusion and a second point defined on the outline of the second protrusion, the imaginary line passing through each of the first point on the first protrusion and the second point on the second protrusion, the first protrusion and the second protrusion being below the imaginary line,
wherein the liquid supply portion has an opening open frontward in the depth direction, and
wherein the second point on the second protrusion is positioned frontward of the opening of the liquid supply portion in the depth direction.
