The present invention provides a compact piezoelectric component in which degradation in the characteristic thereof is further suppressed, and a method for manufacturing the same. A SAW device 21 includes a SAW element 16 having an IDT 2 and a conductive pad 3 connected to the IDT 2 formed on a piezoelectric substrate 1; and an external terminal 12. The SAW device 21 also includes an insulating layer 7 having an exciting portion protective opening 9 serving as space for protecting a SAW-exciting portion including the IDT 2 and a conductive opening 8. The external terminal 12 is connected to the conductive pad 3 through a wiring 11 extending in the conductive opening 8.
