Abstract
An optical modulator includes an optical modulation element that is accommodated in a housing. A plurality of lead pins, which are electrically connected to the optical modulation element through wire bonding, are fixed to a lateral wall of the housing. Each of the plurality of lead pins includes a portion that protrudes into an inner space (inner surface side) of the housing. A resonance suppressing structure (for example, a concave portion), which is configured to suppress resonance between the lead pins, is provided in a lateral wall portion to which the plurality of lead pins are fixed.
