    摘要： According to an embodiment, this X-ray tube is provided with a positive electrode that has a target surface, and a negative electrode having a first filament and a focusing electrode. The focusing electrode includes a valley bottom portion, a first sloped surface that gradually slopes upward from the valley bottom portion in the direction of the positive electrode, a first focusing groove, and a first storage groove. θ1 is greater than 0°. The first focusing groove has a longitudinal axis. One end part on a first extension line side of the first focusing groove is closer to a first reference surface than the other end part of the first focusing groove.

    摘要： An x-ray tube is provided with a negative electrode (2) and a positive electrode. The negative electrode has a filament coil (5) and a focusing electrode (10) that includes a valley bottom part (M), a first inclined plane (11) rising from the valley bottom part (M) and inclined in the direction of the positive electrode, a first focusing channel (21), and a first receiving channel (31). The positive electrode has a target surface. θ1 > 0°. The filament coil (5), the first receiving channel (31), and the first focusing channel (21) are positioned more to a third extended line side than a first reference plane (S1). One end part (31e2) of the first receiving channel (31) is closer to the first reference plane (S1) than the other end part (31e1).
