1. An in-vehicle camera comprising:
a lens barrel including at least one lens and being tubular;
a circuit board having a first surface and a second surface opposite to the first surface;
an imaging element disposed on the first surface of the circuit board and on an optical axis of the at least one lens;
a ring member made of a first resin having a first light transmittance with respect to a predetermined wavelength, disposed to protrude in a direction away from the optical axis over an entire periphery of the lens barrel, and having a first surface and a second surface opposite to the first surface; and
a housing portion accommodating at least the circuit board, in which at least a part of the housing portion having a tubular shape, and at least one end surface of the tubular shape is made of a second resin having a second light transmittance smaller than the first light transmittance with respect to the predetermined wavelength, wherein
the one end surface of the tubular shape of the housing portion is fixed with the second surface of the ring member, and
the in-vehicle camera further comprises a third resin disposed on an inner side of the tubular shape of the housing portion over an entire periphery around the optical axis and between the second surface of the ring member and the imaging element in a direction of the optical axis, and having a third light transmittance smaller than the first light transmittance with respect to the predetermined wavelength.
