A piezoelectric component (1), which serves in particular as a piezoelectric sensor or a piezoelectric actuator, comprises a main body (2). The main body (2) has a first ceramic layer (15), a second ceramic layer (16) and an inner electrode layer (17). An outer metallization (5) is provided here, applied to an outer side (3) of the main body (2) and contacting the inner electrode layer (17). The main body (2) has a removal of material (4), the removal of material (4) separating the outer metallization (5) from an end-face outer electrode (7), which is formed by a metallization (7) of an end face (6) of the main body (2). A method for producing a piezoelectric component (1) is also provided.
A piezoelectric component (1) with a main body (2), which has a first ceramic layer (15), a second ceramic layer (16) and an inner electrode layer (17), an outer metallization (5) being provided, applied to an outer side (3) of the main body (2) and contacting the inner electrode layer (17), the main body (2) having a removal of material (4) and the removal of material (4) separating the outer metallization (5) from an end-face outer electrode (7), which is formed by a metallization (7) of an end face (6) of the main body (2).
A method for producing a piezoelectric component (1), comprising applying an outer metallization (5) to an outer side (3) of a block (30) in rod form, which has a multiplicity of ceramic layers (15, 16, 32-36) and a multiplicity of electrode layers (17, 37-41) arranged between the ceramic layers (15, 16, 32-36), cutting off a main body (2) from the block (30) in rod form, removing a removal of material (4) from the main body (2), forming a metallization (7), which forms an end-face outer electrode (7), on an end face (6) of the main body (2), and configuring the removal of material (4) such that the outer metallization (5) is separated from the end-face outer electrode (7) by the removal of material (4).
