Abstract: Provided is an accurately processed imaging element that can be readily manufactured for saving time and cost. A blade section 2 in which projecting punch blades 22 are arranged on a metal block 21, each punch blade having two sides 22a and 22b corresponding to the two mirror surfaces 31a and 31b of micro holes 31 to be formed in a substrate 3, is lowered for pressing the blades into contact with the substrate 3 with a lifting section 13 and punching the substrate 3 with the punch blades 22, while being vibrated with ultrasonic oscillation section 12.

Abstract: A vacuum blood collection tube (100) comprises a bottomed tube (101) composed of a low temperature resistant material that is less susceptible to low temperature fracture when cryopreserved at ultra-low temperature, a stopper (102) having a needle piercing portion (113) composed of a rubber material that can be pierced with a blood collection needle (110), and a cryopreservation cap (103) composed of the low temperature resistant material. Before blood collection, the stopper (102) is attached to the bottomed tube (101) to maintain the reduced pressure state inside the bottomed tube (101). Thus, blood collection by a vacuum blood collection method is possible. After blood collection, the cryopreservation cap (103) is attached to the bottomed tube (101), so that the liquid tight state of the bottomed tube (101) is maintained, and cryopreservation at ultra-low temperature as it is possible.
