Abstract
An electronic component is constructed to prevent damage and stripping off or separation at adhered portions thereof even if the component is exposed to abrupt temperature changes to thereby provide a highly reliable component. A piezoelectric vibrating element defining a first substrate and an electronic component case including a pair of substrates which are second substrates are adhered together through an adhesive layer so as to define a closed space. The adhesive layer includes a fillet portion which is arranged to extend along lateral walls of the recess to edges of the closed space to prevent separation at adhesion interface surfaces of the substrates.
