<p>PROBLEM TO BE SOLVED: To increase a strength of a lead without increasing self-inductance and self-capacitance of the lead by a method wherein a portion to which adhesives of an inner lead are not adhered is twisted. SOLUTION: As an inner lead 203 is twisted, a strength in upper and lower directions of the inner lead 203 can be increased. For this reason, it is possible to suppress a deformation of the lead due to a stress of injection resin caused conventionally when a resin sealing step is performed. Further, as the inner lead 203 is twisted, a width of the inner lead 203 is apparently fined. Therefore, it is possible to reduce self-inductance and self-capacitance of the inner lead 203. Moreover, as a space of the adjacent inner lead 203 is widened due to the twisting, it is possible to reduce mutual inductance and mutual capacitance between the adjacent leads, and to enhance manufacturing yield and performance.</p> |
