Abstract
An H-type ceramic resonator having two resonating leaves, a connecting leaf for bridging the two resonating leaves to form an H-shape, and electrodes disposed on at least both surfaces of the resonating leaves. The resonator has a dimensional relationship which falls within the following equities: EQU B.sub.2 /B.sub.3 =4 to 6, EQU B.sub.1 /B.sub.3 =2 to 4, and EQU L/B.sub.1 =5 to 6 wherein L is a length of each of the resonating leaves, B.sub.1 is a width of each of the resonating leaves, B.sub.2 is a distance between the two resonating leaves, and B.sub.3 is a width of the connecting leaf.
