Abstract
A piezoelectric device includes a piezoelectric element, a package, a temperature sensitive component and a conductive adhesive. The package includes a base body and a connection conductor. The base body has electric insulation and configures a space. The space is sealed and holds the piezoelectric element. The connection conductor is located on a predetermined surface of the base body. The predetermined surface is on an outer side relative to the space. The temperature sensitive component includes apart terminal and converts temperature to an electrical signal. The conductive adhesive is configured by a thermosetting resin containing a conductive filler and is bonded to the connection conductor and the part terminal.
