A needle selection module finger (30) is comprised of a finger member (31) and a finger holding member (40). The finger member (31) has a butt abutting portion (33) and a support (34). The support (34) has projections (35, 36) at its lower part. The finger holding member (40) has, from its one end toward the other end, a connecting portion (41) having concave parts (42, 42a) for accommodating the projections (35, 36) at the lower part of the support (34), a finger pivot support (43), and a piezoelectric body engaging portion (45). The finger member (31) and finger holding member (40) are positioned by inserting the projections (35, 36) of the finger member (31) in the concave parts (42, 42a) of the finger holding member (40), and are integrally connected to each other by inserting a pin 50 in holes (37, 37a) formed in the projection (35) and a connecting portion (41).
