In a lattice-like pixel structure in which a reflecting plate that reflects a fluorescent light from a fluorescent material-based neutron detecting sheet is arranged along a vertical axis at a regular interval, and a reflecting plate that reflects a fluorescent light is arranged along a horizontal axis at a regular interval and at a right angle with respect to a series of fluorescent plates formed arranged along the vertical axis, a lattice-like fluorescent light detecting member is formed by providing such a structure that a groove may be formed at upper half position of the vertical axis direction reflecting plate and at a center position in a vertical axis interval for accommodating a wavelength shifting fiber for vertical axis detection for detecting the fluorescent light, and a groove may be formed at lower half position of the horizontal axis direction reflecting plate and at a center position in a horizontal axis interval for ...
