1. A shaft-equipped heater unit comprising: a heater plate that heats an object to be heated placed thereon; anda shaft that supports the heater plate,whereinthe shaft is formed by spraying, on a rear surface of the heater plate, material powder which constitutes the shaft on the heater plate at a temperature lower than a melting point of the material powder by heated compressed gas, andthe material powder bites into the rear surface of the heater plate at an interface between the shaft and the rear surface of the heater plate. 2. The shaft-equipped heater unit according to claim 1, wherein the heater plate is constituted of a metal or alloy having high thermal conductivity, andthe shaft is constituted of a metal or alloy having lower thermal conductivity than the material constituting the heater plate. 3. The shaft-equipped heater unit according to claim 1, wherein the shaft comprises a heat-conduction suppressor that suppresses heat conduction from the heater plate to the shaft in a cylindrical body part thereof. 4. The shaft-equipped heater unit according to claim 3, wherein the heat-conduction suppressor is a heat insulation groove. 5. The shaft-equipped heater unit according to claim 1, wherein the shaft is formed of a first material identical to material constituting the heater plate and a second material having lower thermal conductivity than the material constituting the heater plate, andan end of the shaft on the side in contact with the heater plate is formed of the first material as a main component, and proportion of the first material constituting the shaft decreases gradually from the end on the side of the heater plate to another end. 6. A shaft-equipped heater unit comprising: a heater plate that heats an object to be heated placed thereon; anda shaft that supports the heater plate, whereinthe shaft is formed by spraying material powder which constitutes the shaft on the heater plate at a temperature lower than a melting point of the material powder by heated compressed gas anda cylindrical shaft body part of the shaft includes a cooling medium channel. 7. A method for manufacturing a shaft-equipped heater unit comprising a heater plate for heating an object to be heated placed thereon and a shaft for supporting the heater plate, the shaft-equipped heater unit manufacturing method comprising: a shaft forming step of forming the shaft by spraying material powder, which constitutes the shaft, on the heater plate at a temperature lower than a melting point of the material powder by heated compressed gas. 8. The shaft-equipped heater unit manufacturing method according to claim 7, wherein the shaft forming step comprises: a first spraying step of spraying material powder, which constitutes the shaft, on the heater plate at a temperature lower than a melting point of the material powder by heated compressed gas;a groove forming step of forming a heat insulation groove on the shaft formed at the first spraying step; anda second spraying step of, after the groove forming step, further spraying material powder which constitutes the shaft on the shaft on which the heat insulation groove has been formed at a temperature lower than a melting point of the material powder by heated compressed gas. 9. The shaft-equipped heater unit manufacturing method according to claim 7, wherein the shaft forming step comprises: a first spraying step of spraying material powder, which constitutes the shaft, on the heater plate at a temperature lower than a melting point of the material powder by heated compressed gas;a pipe placing step of placing a cooling medium pipe in the shaft formed at the first spraying step; anda second spraying step of, after the pipe placing step, further spraying material powder which constitutes the shaft on the shaft in which the pipe has been placed at a temperature lower than a melting point of the material powder by heated compressed gas. 10. The shaft-equipped heater unit manufacturing method according to claim 7, wherein the shaft is formed of a first material identical to material constituting the heater plate and a second material having lower thermal conductivity than the material constituting the heater plate, andan end of the shaft on the side in contact with the heater plate is formed of the first material as a main component, and proportion of the first material constituting the shaft decreases gradually from the end on the side of the heater plate to another end.
