Abstract
A dynode () constituting an electron multiplier or a photomultiplier is provided with eight rows of channels () each defined by an outer frame () and a partitioning part () of the dynode (). In each channel (), a plurality of electron multiplying holes () are arranged. In specified positions of the outer frame () and the partitioning part () of the dynode (), glass receiving parts () wider than the outer frame () and the partitioning part () are provided integrally with the dynode (). Glass parts () are bonded to all the glass receiving parts (). The glass parts () are bonded by applying glass to the glass receiving parts () and hardening the glass and each have a generally dome-like convex shape. Each dynode () is formed after the dome-like glass part () is bonded to the glass receiving part ().
