A blood filter device which includes: a housing having a dome (2) with an inlet, a filter retaining portion (3) positioned below the dome, and a bottom portion (4) with an outlet; and a filter (8) mounted in the filter retaining portion. A filter sheet (8a) forms pleats, and ridgelines of the respective pleats traverse the filter retaining portion. The device further includes an annular holder (9) intervening between the filter retaining portion and the filter, an annular rib substrate (10) disposed facing the ridgelines of the pleats and having ribs inserted respectively between the pleats; and a bonding resin (11) supplied into outer periphery of the filter including the annular holder and the annular rib substrate, bonding the outer periphery of the filter to the filter retaining portion. Gaps are ensured between the pleats of the filter, enabling air bubbles to be removed easily. |
