PROBLEM TO BE SOLVED: To prevent generation of metal scraps which cause contamination, even when used repeatedly.SOLUTION: A heat sealer 10 includes: a first pressure contact part 11 and a second pressure contact part 12 for sandwiching an object to be sealed; and a heater 13 for heating the first pressure contact part and the second pressure contact part. It also includes: a first grip part 14 connected to the first pressure contact part, and made of PEEK resin, PPS resin or PA resin; and a second grip part 15 connected to the second pressure contact part and made of resin. The second grip part has a through-hole 20 for penetrating the second grip part. By the first grip part passing the through-hole, the first grip part and the second grip part cross each other. At a crossing position, a shaft part 21 is provided, and a twisted spring 22 is wound around the shaft part. In the twisted spring, one end side extends by passing through the first grip part, the other end side extends by passing through the second grip part, and the first grip part and the second grip part are energized in a direction of being separated from each other.SELECTED DRAWING: Figure 1 【課題】繰り返し使用してもコンタミネーションの原因となる金属屑の発生を防止できるようにする。【解決手段】ヒートシーラー１０は、被シール物を挟み込むための第１圧接部１１及び第２圧接部１２と、該第１圧接部及び第２圧接部を加熱するためのヒータ１３とを備え、さらに、第１圧接部に接続され、ＰＥＥＫ樹脂、ＰＰＳ樹脂、又はＰＡ樹脂からなる第１把持部１４と、第２圧接部に接続され、上記樹脂からなる第２把持部１５とを備えている。第２把持部は、該第２把持部を貫通する貫通孔２０を有し、第１把持部が貫通孔を通過することにより、第１把持部と第２把持部とは互いに交差し、交差する部分には軸部２１が設けられ、軸部には捻りばね２２が巻き付けられ、捻りばねは一端側が第１把持部の中を通って延び、他端側が第２把持部の中を通って延び、第１把持部及び第２把持部を互いに離間する方向に付勢させる。【選択図】図１
