- the second member 3 can be made of silicon nitride.
- the first member 1 may include alumina, and the second member 3 may include zirconia.
- the second member 3 at the tip of the heater 10 is a member having high elasticity, it is possible to reduce the risk of the second member 3 being damaged when the heater 10 pierces the object to be heated.
- the second member 3 may have a shape that becomes thinner toward the tip. Thereby, it is possible to easily pierce the heated object with the tip of the heater 10.
- the second member 3 has a conical shape.
- a shape in which a cylindrical portion and a conical portion are combined may be used.
- the bottom surface of the cylindrical portion has a circular shape having the same diameter as the end surface of the first member 1, and the bottom surface of the conical portion has a circular shape having the same diameter.
- the shape of the second member 3 of the present example can increase the volume of the second member 3 as compared with the shape shown in FIG. By increasing the volume of the second member 3 having a low thermal conductivity, the end surface of the first member 1 can be protected by the second member 3 while further lowering the temperature at the tip of the heater 10.
- the tip portion may be curved (R-shaped).
- the first member 1 and the second member 3 may be joined by a glass material 4. Thereby, the bonding strength between the first member 1 and the second member 3 can be increased.
- the first member 1 is a columnar member, and the shape of the end surface of the first member 1 is circular. The shape of the surface to be joined may be circular. In this case, since the bonding area of the glass bonding can be increased, the strength of the heater 10 can be further increased.
- the first member 1 and the second member 3 are joined by a glass material 4, and the outer peripheral surfaces of the first member 1 and the second member 3 are covered with the glass material 4.
- the heater 10 pierces the object to be heated, the possibility that the object to be heated adheres to the surface of the heater 10 can be reduced.
- corrosion of the heater 10 at a portion where the object to be heated adheres can be reduced, and the possibility of the heater 10 being damaged can be reduced.
- the durability of the heater 10 can be improved.

Thereby, the inside of the concave portion 31 becomes a space, and the thermal conductivity from the first member 1 to the second member 3 is reduced, so that the temperature at the tip of the heater 10 can be reduced.
- the first member 1 may have the concave portion 12 on the end face, and the end face of the second member may be a flat surface. Thereby, the inside of the concave portion 12 becomes a space, and the thermal conductivity from the first member 1 to the second member 3 is reduced, so that the temperature at the tip of the heater 10 can be reduced.
- the glass material 4 may enter the concave portions 31 and the concave portions 12.
- the first member 1 may be cylindrical. Thereby, the heat capacity of the heater 10 can be reduced. Therefore, heat can be easily transmitted to the object to be heated. As a result, the heating speed of the object to be heated can be increased.
- the second member 3 may have the protrusion 32 on the end face, and the protrusion 32 may be inserted inside the first member 1 having a cylindrical shape. This makes it possible to increase the bonding strength between the first member 1 and the second member 3 while reducing the heat capacity of the heater 10.
