1. An optical module comprising:
a wiring board;
an optical modulator arranged on the wiring board, the optical modulator having a cutout portion and a first terminal projecting to the inside of the cutout portion, the optical modulator being configured to perform optical modulation by using an electrical signal input to the first terminal;
a driver arranged on the wiring board, at least a part of the driver being housed inside the cutout portion, the driver being configured to generate an electrical signal;
an electrode pattern on the wiring board, the electrode pattern extending from the driver inside the cutout portion, the electrode pattern being configured to transmit the electrical signal generated by the driver; and
a flexible board having flexibility, one end of the flexible board being electrically connected with the first terminal inside the cutout portion, another end of the flexible board extending in the direction away from the driver, the flexible board being electrically connected with the electrode pattern and configured to input the electrical signal transmitted by the electrode pattern to the first terminal.
