PROBLEM TO BE SOLVED: To provide a sample suction pipe which is easy to manufacture, is advantageous in terms of cost, has relatively large strength, has long service life, and can prevent trouble such as clogging with residue, sample leakage, etc. SOLUTION: A sample suction pipe P is for sucking and sampling blood in a sample container via a rubber cap, and consists of a suction capillary 10, a ventilating capillary 20, and a holder 30. The capillaries 10, 20 are made of the same stainless steel. The holder 30 is made from a polyacetal resin. After the capillaries 10, 20 are arranged parallel to each other with their ends aligned, they are welded and integrated together along the ends of their portions, where their circumferential wall surfaces make contact with each other. A suction opening 13 and a ventilating opening 23 are bored in the circumferential wall surfaces of the capillaries 10, 20, respectively. |
