[Problem to be Solved] A diamond crystal which can be formed to a large area, and has a high orientational property and a reduced FWHM is provided. [Solution] As the diamond crystal, a diamond crystal in a bulk form including dislocation concentration regions is formed. An interval between each of the dislocation concentration regions is from 10 nm to 4000 nm. The crystal orientation of crystal main face at the surface of the diamond crystal is any one of (100), (111), or (110). An external shape of the diamond crystal in a surface direction is a rectangle, a circle, or a circle having an orientation flat plane. The rectangle is set to have a side length of not less than 8.0 mm. The circle is set to have a diameter of not less than 8.0 mm.

[Object] A configuration of a tubing pump capable of improving flow rate accuracy which is required, particularly, in infusion pumps for medical use is realized. [Solving Means] In a tubing pump that transfers a liquid in a tube which is detachably installed, a pump mechanism includes a valve mechanism unit that blocks up and opens the installed tube and a tube pressing mechanism unit that repeatedly presses the tube, and the tube pressing mechanism unit includes a pump block that is movably held by at least two guide shafts.

A structure of a vibrator to increase reliability in an electrical connection between power supply terminals of and circuit board electrodes of the vibrator, and to improve mounting efficiency of the vibrator on a circuit board. In the structure, the terminals are constructed from twisted coil springs, and contact portions of the terminals, which portions are in contact with the electrodes, are made in a winding form. The twisted coil springs each are wound around a pivot pin, and steps as clearance for the contact portions and surface portions to which the contact portions are opposed face to face are provided. However, alternatively to the steps and surface portions above, any of the following structures can be adapted: providing a partition plate between two power supply terminals, or surrounding spaces, in which the contact portions can elastically deform, by insulative box members, or extending the twisted coil spring portions to the contact portions asymmetrically in a positive and a negative electrode so that, when the power supply terminals are elastically deformed, each of the contact portions to be deformed more outward than each of the coil spring portions.
