PROBLEM TO BE SOLVED: To provide a piezoelectric transducer and a piezoelectric component capable of ensuring a high Q value by suppressing sub-oscillation that occurs other than thickness sliding oscillation being main oscillation. SOLUTION: A piezoelectric substrate 3 has first grooves 41 to 44, second grooves 45 and 46. The first grooves 41 to 44 extend in a lengthwise direction along a side part in a widthwise direction of oscillation electrodes 1 and 2. The second grooves 45 and 46 extend in a widthwise direction outside the area of the oscillation electrodes 1 and 2. COPYRIGHT: (C)2007,JPO&INPIT
