An optical module according to an embodiment includes: a barrel including an accommodating portion; and a lens portion disposed inside the accommodating portion and including a first lens, a second lens, and a third lens. The barrel includes a first inner wall portion, a second inner wall portion, and a third inner wall portion inside the accommodating portion. The first lens includes glass. The second lens and the third lens include plastic. Moreover, the lens diameter of at least one of the first lens, the second lens, and the third lens satisfies the following formula represented by 2 mm <= lens diameter <= {40 ㎛ / (barrel linear expansion coefficient (ppm/℃) - lens linear expansion coefficient (ppm/℃)) * temperature change (℃)}.
