PURPOSE:To keep the straight pores and to freely control a size of pores by perpendicularly erecting whisker metal having specified diameter to a metal substrate. CONSTITUTION:The whisker metals 2 in diameter of 0.5-10mum are provided in parallel in the longitudinal direction and perpendicularly erected on a thin plate 1. Namely, the whisker metals 1 are scattered on the thin plate 1 by the dry method, a sintering furnace to which the vertical or horizontal magnetic field is applied externally is used as the electric furnace for sintering, and the magnetic field is continuously applied from the timing before start of sintering to the timing after the end of sintering. Thereby, angle formed by the longitudinal direction of whisker metal 2 and the thin plate 2 and interval, namely a size of pores may be controlled freely. |
