| Zusammenfassung: | The invention provides a plunger and a method of manufacturing plunger. A first plunger (110) includes a first tip contact (112), a first columnar portion (114), and a first backing portion (116). The first tip contact (112) is formed by embedding a first conductive material in a recess (602A) provided in a metal substrate (600A). The first columnar portion (114) is formed by embedding a second conductive material in a first opening (612) provided in a first resist film (610) formed on a metal substrate (600A) and located above the recess (602A). The first backing portion (116) is formed by embedding a third conductive material in a second opening (622) provided in a second resist film (620) formed on the first resist film (610) and located above the first opening (612). |
