ELECTRONIC COMPONENT AND MANUFACTURING METHOD THEREFOR

To enhance airtightness of an electronic component and also enhance vibration resistance.SOLUTION: An electronic component includes an exterior case having an accommodation portion in which a first case member (6) having a first opening portion (23) covering an upper surface side of a lead terminal (12) and a second case member (8) having a second opening portion (32) covering a lower surface side of the lead terminal are joined to each other to accommodate an element, and a lead terminal lead-out portion for confronting the first opening portion and the second opening portion with each other, pinching the lead terminal by the overlapping first opening portion and the second opening portion, and protruding the lead terminal to the outside of the accommodation portion. Further, there are provided inclined surfaces that narrow the opening width in a direction in which the side surfaces of the first opening portion and the second opening portions are spaced apart from a joint portion of the first case member and the second case member, the opening width on the joint portion side of the first opening portion and the second opening portion is wider than that of the lead terminal, and the narrowest portion of the opening width is equal to or less than the width of the lead terminal.SELECTED DRAWING: Figure 3 【課題】電子部品の気密性を向上させるとともに、耐振動性を向上させる。【解決手段】リード端子（１２）の上面側を覆う第１の開口部（２３）を有する第１のケース部材（６）とリード端子の下面側を覆う第２の開口部（３２）を有する第２のケース部材（８）を接合して素子を収納する収納部を備える外装ケースを備え、第１の開口部と第２の開口部が開口面を対向させ、重なり合った第１の開口部と第２の開口部でリード端子を挟持し、収納部の外部にリード端子を突出させるリード端子導出部を備える。また第１の開口部と第２の開口部の側面が第１のケース部材と第２のケース部材の接合部から離間する方向に、開口幅を狭小にする傾斜面であり、第１の開口部と第２の開口部の接合部側の開口幅がリード端子よりも幅広であり、かつ、開口幅の最も狭小部分がリード端子の幅以下である。【選択図】 図３
