Liquid jet head and liquid jet device

A liquid jet head comprising:

• a first head chip and a second head chip stacked on one another in a first direction, and each adapted to jet liquid;
• a first flow channel member disposed on an opposite side of the first head chip to the second head chip in the first direction, and including an inflow port communicated with a supply source of the liquid and a first liquid flow channel adapted to communicate the inflow port and the first head chip with each other;
• a second flow channel member disposed on an opposite side of the second head chip to the first head chip in the first direction, and including a second liquid flow channel communicated with the second head chip;
• and
• a communication flow channel located between the first flow channel member and the second flow channel member, and adapted to communicate the first liquid flow channel and the second liquid flow channel with each other, wherein
• the first liquid flow channel includes a first supply flow channel opening the first head chip, the liquid flowing through the first supply flow channel inflowing into the first head chip, and
• the second liquid flow channel includes a second supply flow channel opening the second head chip, the liquid flowing through the second supply flow channel inflowing into the second head chip.
