An impact detector (100) includes a weight (510), a case (400,200) in which a transition path (231) for the weight (510) is formed, a planar elastic member (320) extending in the case (400,200) with a first end oriented in a direction in which the weight (510) moves upon an impact in a first direction, a fixing member (242,2687,462) fixing the planar member to the case (400,200). The planar elastic member (320) includes a folded portion (323), a first arm (321) having an end holding the weight (510) at an initial position, that deforms to release the weight (510) upon the impact, and a second arm (322).
The fixing member (242,268,462) includes a sandwiching portion (242,462) sandwiching a center portion of the folded portion (323) and a contact portion (242b,242c) in contact with the first arm (321) and the second arm (322). A packaging container (700) includes the impact detector (100). |
