（ｄ）に示すオシレータ用ステムを製造する。First, for example, four standoff insertion holes 2 are formed in a metal base 1, and an insulation tube insertion hole 3 for inserting an insulation tube described later and a lead insertion hole (for grounding) 4 are formed.
Are formed respectively (see FIG. 5 (a)). Subsequently, a sealing jig 6 having appropriate cylindrical openings 5a and 5b on its surface is prepared, and then the base 1 is placed on the sealing jig 6. Next, the cylindrical insulating material 7 is inserted into the stand-off insertion hole 2 of the base 1 until the upper surface of the insulating material 9 coincides with the upper surface of the stem body 1, and the insulation inside the insulating tube insertion hole 3 is performed. Lead to the lead insertion hole (for terminal) 8a of tube 8
9 1 and lead through the lead insertion hole 4 and the roller 10
9 2 are respectively inserted (shown in FIG. 5 (b)). After that, the sealing jig 6 is put in a heating furnace (not shown) and heated at a high temperature, so that the insulating material 7 protruding from the lower surface side of the base 1 can be obtained.
Is melted to form a standoff 11 having a spherical lower end (shown in FIG. 5 (c)). Here, the reason that the lower end portion of the standoff 11 is spherical is to prevent the back surface of the substrate from being damaged when the base is mounted on the substrate or the like. Then, the sealing jig 6 is taken out of the heating furnace, and the sealing jig 6 is removed to manufacture the oscillator stem shown in FIG. 5 (d).

Base 1 when melted to form standoffs 11
The insulating material 7 easily flows out to the lower surface of the. Therefore, a gap is likely to be formed between the standoff 11 and the base 1 after melting and cooling. As a result, cracks are likely to occur, and rust is likely to occur at the base portion of this gap, resulting in unstable quality.

すオシレータ用ステムを製造する。First, while forming, for example, four standoff insertion holes 2 in a metal base 1 (for example, an iron-based alloy), an insulation tube insertion hole 3 for inserting an insulation tube described later, a lead insertion hole (for grounding) 4) are formed (see FIG. 1 (a)). Here, the standoff insertion hole 2 has a tapered portion 2a at the lower end thereof. Next, the sealing jig 6
Prepared. The sealing jig 6 includes the standoff insertion hole 2 of the base 1, the insulating cylinder insertion hole 3, and the lead insertion hole 4
2 have openings 5a and 5b respectively, and the opening 5a corresponding to the standoff insertion hole 2 has the following relationship with the standoff insertion hole 2. That is, as shown in FIG. 3, the diameter (D 1 ) of the opening 5a is equal to that of the standoff insertion hole 2
Is larger than the inner diameter (D 2 ) and smaller than the chamfer diameter (D 3 ). Next, the base 1 is placed on the sealing jig 6, and the stand-off insertion hole 2, the insulating cylinder insertion hole 3, and the lead insertion hole 4 provided in the base 1 are the openings of the sealing jig 6.
They were placed so that they were located on 5a and 5b, respectively. Further, the cylindrical insulating material 7 is inserted into the stand-off insertion hole 2 of the base 1 until the upper surface of the insulating material 7 coincides with the upper surface of the base 1, and the insulating cylinder in the insulating cylinder insertion hole 3 is inserted. The lead 9 1 is inserted into the lead insertion hole (for terminal) 8a of 8 and the lead 9 2 is inserted into the lead insertion hole 4 (shown in FIG. 1 (b)). After this,
By placing the sealing jig 6 in a heating furnace (not shown) and heating it at a high temperature, the insulating material 7 protruding from the lower surface side of the base 1 is melted and a standoff 21 having a spherical lower end is formed ( FIG. 1 (c) is shown). Then, the sealing jig 6 is taken out from the heating furnace, and the sealing jig 6 is removed to manufacture the oscillator stem shown in FIG. 1 (d).

Since the insulating material 7 is melted by making the diameter larger than the inside diameter (D 2 ) of the standoff insertion hole 2 and smaller than the chamfering diameter (D 3 ), the insulating material 7 does not flow out to the lower surface of the base 1 during melting. , It is possible to prevent a conventional gap from being generated between the standoff 10 and the base 1 after melting. Therefore, unlike the conventional case, the base 1 is free from rust and is excellent in strength, and as shown in an enlarged view in FIG. 4, a standoff 21 having a spherical projection from the lower surface of the base can be formed.
