An article transport apparatus includes a first belt conveyor (11), and a second belt conveyor (12) adjacent to the first belt conveyor (11) on a second side in the width direction (W2). The first belt conveyor (11) includes a first belt member (11B) forming a first transport surface (11F), and a second belt conveyor (12) includes a second belt member (12B) forming a second transport surface (12F). The first transport surface (11F) is configured to allow an article being transported to be placed thereon, and is inclined downward toward the second side in the width direction (W2), the second transport surface (12F) is configured to come into contact, from the second side in the width direction (W2), with the article placed on the first transport surface (11F), and a surface friction coefficient (μ1) of the first belt member (11B) and a surface friction coefficient (μ2) of the second belt member (12B) are different from each other.
