Technical Examples

A surface mounting base for an oscillator that is provided with: an insulation base comprising a casing wall having a through hole; a sealing glass that is filled into the through hole and forms a space part on one principal surface side of the insulation base; and a J lead terminal, which passes through the sealing glass and clamps an inner surface and an outer surface of the casing wall, and which has a holding part for a crystal element on a top surface of the sealing glass that is one principal surface side of the insulation base, and which has a tip end part bent in a concave shape projecting from a bottom surface of the sealing glass and extending from the inside of the casing wall towards the outside across a tip end surface, and in which the tip end part is soldered to the insulation base. Moreover, a base part of the J lead terminal projects below the bottom surface of the sealing glass, and the inner surface of the tip end part is distanced from the bottom surface of the sealing glass by at least the thickness of the J lead terminal or more. As a result, a surface mounting base in which distortion of the insulation base and the set substrate is cancelled, and compatibility is well maintained, and a highly reliable crystal oscillator which uses this surface mounting base are provided.
