- the seal ring 4 is used, it is larger than the width of the seal ring 4. Therefore, a part of the metallized layer formed on the upper surface of the second insulating member is not covered with the first side wall part 21 and the second side wall part 22 or the seal ring 4, and the first side wall part is formed. 21 and the second side wall 22 are exposed on both sides. Therefore, when this metallized layer and the frame 2 are joined with a brazing material, an excess brazing material for joining the input / output member 3 to the hole 20 is stored in this exposed portion.
- the brazing material collected causes a meniscus between the side surface of the frame body 2 or the side surface of the seal ring 4 and improves the bonding strength between the input / output member 3 and the frame body 2. And the sealing reliability of the electronic device 100 is improved.

- the constricted portion 30 is formed on the upper surface 3a joined to the first side wall portion.
- the metallized layer is not formed on the inner side surface of the input / output member 3. Therefore, the flow to the lower surface side of the brazing material that fixes the upper surface 3 a of the input / output member 3 is blocked by the constricted portion 30. And sufficient brazing
- wax material can be collected on the upper surface 3a of the input / output member 3, and joining of the input / output member 3 and the frame 2 or the seal ring 4 can be made sufficient.
- the constricted portion 30 is formed by a concave groove 30 a extending in the vertical direction from the upper end of the wall surface of the input / output member 3.
- the groove 30a By forming the groove 30a on the upper surface 3a, the width of the upper surface 3a becomes narrower at the portion where the groove 30a is formed.

- the constricted portion 30 only needs to be able to narrow the width of the upper surface 3a and the width of the metallized layer, and is not limited to the concave groove 30a, and may be formed by other means.
- the constricted portion 30 may be formed by providing a notch in the side portion of the upper surface 3a.
- the concave groove 30a is formed will be described.
- the metallized layer is not applied to the side wall surface of the second insulating member. Therefore, the surplus brazing material does not wet and spread the side wall surface of the input / output member 3. As a result, surplus brazing material does not adhere to the wiring conductor 32 to cause an electrical connection failure such as a short circuit.
- the width of the upper surface 3a of the input / output member 3 exposed from the outside of the first side wall portion 21 is, for example, 0.17 mm.
- the width of the upper surface 3a of the input / output member 3 exposed from the inside of the first side wall portion 21 is, for example, 0.53 mm.
- the depth of the concave groove 30a is 0.15 mm. Therefore, the distance between the bottom surface of the groove 30a and the first side wall portion 21 is 0.38 mm. That is, the width of the upper surface 3a is 0.53 mm to 0.38 mm at the position of the concave groove 30a.
- the brazing material is difficult to flow through this width.
- the bottom surface of the concave groove 30a is not disposed so as to overlap the lower side of the first side wall portion 21 or the seal ring 4.
- the bottom surface of the concave groove 30a is preferably formed so as to be positioned in the direction inside the package relative to the inner surface of the seal ring 4. It is possible to reduce the possibility that the thermal stress generated in the concave groove 30a due to the difference in thermal expansion with the seal ring 4 deforms the input / output member 3 and is significantly damaged.
- the width of the upper surface 3a may be anything as long as it can block the flow of the brazing material, and an effect is obtained if it is narrowed by 30% to 90% of the width of the upper surface 3a. Preferably, it may be 50% to 80% of the width of the upper surface 3a.

As a result, a sufficient amount of brazing material can be accumulated between the formation positions of the two concave grooves 30a on the upper surface 3a. If it is provided only on one side, the brazing material may flow through the other side.
- the concave groove 30a is preferably provided at an approximately equal distance from the second side wall portion 22 on both inner wall surfaces of the first side wall portion 21a and the other first side wall portion 21b.
- the amount of the brazing material flowing on the first side wall portions 21a, 21b side on both sides becomes equal, and the joining force with the first side wall portions 21a, 21b of the input / output member 3 can be made equal.
- brazing material amount is substantially equal, and joining force Should be balanced.
- a concave groove 30 a may be provided on the outer wall surface of the input / output member 3.

- the concave groove 30a is provided in a curved shape between the bottom surface and the inner surface. Thereby, it is suppressed that the thermal stress which arises by the thermal expansion difference with the frame 2, the input / output terminal 3, and the seal ring 4 concentrates on a part between the bottom face and inner surface of the ditch
- FIG. 2 shows an example in which the wiring conductors 32a and 32b and the wiring conductors 32c and 32d are arranged in two rows from the bottom surface of the concave groove 30a toward the end surface of the protruding portion 31a.
