PURPOSE:To provide a production method of porous catheter with branch pipe in which a resin film formed in the passage end of the main body for forming a catheter in the joint part is not peeled off due to setting by enzyme reaction to prevent a suction failure CONSTITUTION:In forming a joint part 3 having a passage which passes through a main body 1 forming the catheter with several passages 4,... in it and branch pipes 2, 2'... for each passage by resin molding, a part of resin for forming the joint part is injected to the passage end of the main body to form a thin resin film 7 to make an integrated structure. A pair of electrodes 20 and 20 are inserted from each opening end of the branch pipes 2, 2'... to the passage end of the main body in the joint part 3 separately, and a high frequency voltage is applied to the electrodes 20 and 20 to fuse the resin film 7 in the passage end of the main body in the joint part 3 by the high frequency dielectric heating. |
