Abstract
An ink jet apparatus includes: a head that discharges liquid; a circuit substrate that has a drive circuit for driving the head; a heat sink which has a part that is in direct or indirect contact with the circuit substrate and is able to dissipate heat generated in the circuit substrate; and a fan that generates air flow capable of cooling the heat sink. The heat sink is configured such that the air flow is not directly blown against the drive circuit and such that the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit.
