<p>Disclosed is a composite component that reduces unwanted interference generated between a plurality of signal types. Also disclosed is a circuit board (10) with a branching filter mounted thereon. The board main body (12) has main surfaces (S1, S2). External electrodes (14a to 14c) are provided on one main surface (S1). External electrodes (16a to 16c) are provided on one main surface (S2). Signal paths (SL1 to SL3) each connect the external electrodes (14a to 14c) to the external electrodes (16a to 16c). Ground conductors (22a, 22b) are housed in the board main body (12) and overlap with a mounting region (R) where the branching filter is mounted so as to include the mounting region (R), when viewed from above from the z-axis direction. Each signal path (SL1 to SL3), when viewed from above from the z-axis direction, extends from inside the mounting region (R) to outside the mounting region (R) between the main surface (S1) and the ground conductor (22b), and passes through outside the mounting region (R) to connect to the external electrodes (16a to 16c).</p> |
