摘要： A laminated transformer includes a plurality of ferrite sheets having surfaces on which conductor patterns are formed and are laminated and baked to be a sintered body, and a pair of the primary external electrodes and a pair of the secondary external electrodes are provided at end faces of the sintered body. The transformer is used mainly in a high frequency circuit, the conductor patterns formed at the laminated ferrite sheets being used as the primary or the secondary, both ends of the primary conductor patterns being electrically connected to the pair of the primary external electrodes and both ends of the secondary conductor patterns being electrically connected to the pair of the secondary external electrodes, so that the primary and secondary conductor patterns have no coiled construction and no self-distributed capacity, so that the laminated transformer will no induce self-resonance even when used in a high frequency band.
