Provided is a cutter mechanism capable of performing satisfactory cutting stably with a low risk of causing cutting defects. The cutter mechanism includes: a fixed blade (9); a movable blade (8) formed in a substantially V-shape when viewed from above, which is provided slidably with respect to the fixed blade; a fixed blade holder (16) that holds the fixed blade with respect to the movable blade in an inclined state so that a cutting edge (9a) of the fixed blade forms a predetermined cutting angle (&thetas;) with respect to a cutting edge (8a) of the movable blade; a holder support member (17) that is orthogonal to a sliding direction of the movable blade and supports the fixed blade holder movably in an orthogonal direction (L1) in which the cutting edge of the movable blade moves close to and away from the cutting edge of the fixed blade; and a biasing member (40) that is provided between the fixed blade holder and the holder support member, and biases the fixed blade holder in the orthogonal direction so that the cutting edge of the fixed blade is brought into press-contact with the cutting edge of the movable blade.
