PRESSURE SENSITIVE RESISTOR AND PRESSURE SENSITIVE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a pressure sensitive resistor for operating the change of an electric resistance value with high sensitivity and for realizing excellent reproducibility and durability. SOLUTION: This pressure sensitive resistor is constituted of base polymer 10 made of resin in a range in which share hardness is JIS A50 or more and JIS D80 or less, conductive materials 2, and packing materials 3 with elasticity higher than that of the base polymer 10 in which the rate of a mean grain diameter to rough film thickness is 0.25-2. The conductive materials 2 and the packing materials 3 are dispersed in the base polymer 10 and formed like a film.
