A casing of a box-like shape of a rectangular parallelepiped is formed which has one side portion or each of a pair of opposing side portions formed with an opening and has a partitioning member therein. A plurality of plate like piezoelectric resonators and terminal plates are placed in the casing in parallel with the upper and bottom portions of the casing so that the same are housed in a stacked manner. The plurality of piezoelectric resonators and terminal plates as housed are partitioned into two groups by means of the partitioning member. Accordingly, the height of the casing is determined by the thickness of each plate like piezoelectric resonator and the number of the resonators, with the result that the height of the casing can be decreased to be a thin type. A blocking member or members are provided to one opening or two opposing openings formed on the side portion or portions. The piezoelectric resonators and terminal plates are blocked by the blocking member from being slipped out from the casing.
