Abstract: A photodetector comprising: a separation region that is provided in a semiconductor substrate and defines a pixel region; a hole accumulation region that is provided in the semiconductor substrate of the pixel region along a side surface of the separation region; a multiplication region that is provided in the semiconductor substrate of the pixel region and is configured by joining a first conductivity type region and a second conductivity type region from the surface side of the semiconductor substrate in the thickness direction of the semiconductor substrate; and an insulating region provided in the semiconductor substrate in a region between the multiplication region and the hole accumulation region, wherein a formation depth of the insulating region is larger than a formation depth of the first conductivity type region.

Abstract: An acceleration-determination device (D) includes a gripping jig (1) that retains a gripping tool (1g) gripping a test piece (Y) in a state where the gripping tool is tilted from a horizontal state, detects a tilt angle of the gripping tool, and makes it possible to change a gripping force of the gripping tool, a mass adjuster (B) that adjusts a mass of the test piece such that a component force of gravity in a tilt direction which varies according to the tilt angle equals gravity acting on the test piece before tilting thereof, and an acceleration calculator (3b) that calculates an acceleration of the test piece when the test piece is detached from the gripping tool based on the tilt angle and a gravitational acceleration acting on the test piece when the test piece is detached from the gripping tool.
