A lead terminal 5 has a first portion 5a penetrating the first through-hole 2, a second portion 5b penetrating the second through-hole 4, and a third portion 5c arranged between the stem 1 and the flexible substrate 3. Insulating glass 6 fills a gap between the stem 1 and the lead terminal 5 in the first through-hole 2. A wiring pattern 7 is provided on the flexible substrate 3. Solder 8 connects the lead terminal 5 and the wiring pattern 7. The third portion 5c of the lead terminal 5 has a larger lead diameter than the first and second portions 5a and 5b and prevents the solder 8 from flowing out from the flexible substrate 3 side to the stem 1 side.SELECTED DRAWING: Figure 1
