The element-side electrode of a pyroelectric element (10) and the substrate-side electrode of a substrate (20), to which the pyroelectric element is to be attached, are connected to each other by curing a conductive adhesive (60) by having the conductive adhesive (60) between the element-side electrode of the pyroelectric element (10) and the substrate-side electrode of the substrate (20). The conductive adhesive (60) contains an epoxy resin, and has a pencil hardness of 4B-7H as the hardness stipulated in JIS K 5600-5-4 (ISO 15184) in the cured state. In the case of a failure of the pyroelectric element (10), the pyroelectric element (10) is removed from the substrate (20) by applying a shock to the cured conductive adhesive (60) and cutting the conductive adhesive with a cutter.
