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.
