Provided is a crusher capable of omitting a device for feeding a pulp sheet from outside into inside of a casing or suppressing a driving force of this device to be small and an absorber-manufacturing device provided with the same. A pulp sheet (P) is guided to a contact position (m) where the pulp sheet (P) and crushing edges (9b) of a cutter (9) come into contact from a position upstream of a virtual line (L3) orthogonal to a tangent line (L2) of a rotational path (R1) of the crushing edges (9b) at the contact position (m) and passing through the contact position (m) in a rotational direction (Y2) by a guiding section (5a) provided in a casing (5) and configured to guide the pulp sheet (P) from outside into inside of the casing (5).
