<p>[PROBLEMS] To ensure chip strength by preventing a chip main body from being largely chipped by a mounting hole of the chip main body without making the shapes of a clamping member head part and the mounting hole complicated. [MEANS FOR SOLVING PROBLEMS] On the chip, a mounting hole (5) penetrating a chip main body (1) is formed. The chip is pressed with the clamping member (13) provided with a shaft part (13A) inserted into the mounting hole (5) and a head part (13B) having a diameter larger than that of the shaft part (13A), and the chip is clamped to a chip mount (12) by a chip clamping mechanism. In the clamping member (13), a cross section orthogonally intersecting a central shaft line (O) of a rear plane (13C) of the head part (13B) has a circular shape with the shaft line (O) at the center. In the chip main body (1), the head part (13B) of the clamping member (13) is permitted to pass through the mounting hole (5). An opening part of the mounting hole (5) is provided with an abutting part (5B) whereupon a part of the rear plane (13C) of the head part (13B) abuts when the clamp member (13) moves forward.</p> |
