To provide an oscillation detection unit that enables actuating detection without being damaged even if dropping the oscillation detection unit from air to the ground surface.SOLUTION: An oscillation detection unit 1 comprises: a first filler part 121 for filling first filler 131 using a double-fluid hardenable resin to be hardened when mixing the first filler 131 with second filler 132 as filler 130; a second filling part 122 for filling the second filler 132; an actuation part 140 that, when an impact of a prescribed value is applied, opens at least any of a part of the first filling part 121 and a part of the second filling part 122 to thereby mix the first filler 131 with the second filler 132; and a coating material 120 that has an oscillation detection unit 110 detecting oscillation put in place inside, in which when the impact equal to or more than the prescribed value is added, the first filler 131 is mixed with the second filler 132 to get hardened.SELECTED DRAWING: Figure 6 【課題】空中から地上に投下しても損傷することなく検出作動が可能な振動検出ユニットを提供する。【解決手段】充填剤１３０として第１充填剤１３１と第２充填剤１３２とが混合した場合に硬化する二液性硬化樹脂を用い、第１充填剤１３１を充填するための第１充填部１２１、第２充填剤１３２を充填するための第２充填部１２２、所定の値の衝撃が印加された場合に、第１充填部１２１の一部又は第２充填部１２２の一部の内少なくともいずれかを開放して第１充填剤１３１と第２充填剤１３２とを混合させる起動部１４０及び振動を検出する振動検出部１１０を内包する被覆材１２０を備え、所定以上の値の衝撃が加わった場合に第１充填剤１３１と第２充填剤１３２とが混合して硬化するようにした振動検出ユニット１。【選択図】図６
