PROBLEM TO BE SOLVED: To stabilize a plasticized state and an amount of a plasticized material produced in a plasticizing device. SOLUTION: A rotor rotating about a rotation axis and having a groove forming surface on which a groove is formed, a barrel facing the groove forming surface and having a communication hole, and a material supplied between the rotor and the barrel. Provided is a plasticizing device comprising a first heating unit, which plasticizes the material supplied between the rotor and the barrel by rotation of the rotor and heating by the first heating unit, and discharges the material from the communication hole. Will be done. In this plasticizing device, the first heating portion is arranged closer to the groove forming surface than the first portion in the axial direction of the rotation axis and the first portion accommodating the first heat source, and is viewed along the axial direction. It has a second portion, sometimes shaped to surround the communication hole, and is configured to transfer heat from the first heat source to the material between the rotor and the barrel via the second portion.
