Abstract
A detection device including: a holding block that holds a transparent tubular body having a curved surface shape; an accommodating hole that is formed in the holding block and in which the tubular body is inserted and accommodated; an optical sensor that includes a light projecting unit which emits detection light for detecting whether or not the tubular body is accommodated in the accommodating hole and a light receiving unit which receives the detection light; and an optical path of the detection light that has a tunnel structure covered with a wall surface, the optical path linearly extending inside the holding block in a direction intersecting with the accommodating hole and being formed at a position away from a radial center of the accommodating hole, in which a wall surface of the accommodating hole and a wall surface of the optical path have a light reflectivity of 30% or less.
