A magnetic display panel capable of ensuring safety to the body of an infant, permitting drawing of clear lines and ensuring safe disposal thereof. A magnetic display panel (1) includes a core housing (3) which has a peripheral edge (3a) formed to have an increased height and is formed therein with a recess (8), a plate-like face member (2) arranged so as to cover the recess (8), and a core block (5) provided with a number of cells (4) in which a plastic dispersion liquid (7) containing magnetic particles is encapsulated and sealedly joined between the core block (5) and the plate-like face member (2) by an adhesive. The core housing (3) and plate-like face member (2) are each made of olefin synthetic resin. One of the core housing (3) and plate-like face member (2) constitutes a drawing faceplate which is formed to be transparent or semi-transparent. The core block (5) is formed of pulp made paper.

L'invention concerne un tableau d'affichage magnétique (1) offrant toute sécurité, y compris lorsqu'un jeune enfant joue avec, sur lequel on peut toujours tracer des lignes précises, et pouvant être jeter au rebut sans risque pour l'environnement. Un bloc central (5) présente une pluralité de cellules dans lesquelles un liquide de dispersion plastique (7) contient des particules magnétiques. Ce bloc est scellé avec un adhésif entre un corps (3) recevant le bloc central et présentant une cavité (8) formée par relèvement des bords (3a) et une plaque (2) recouvrant la cavité (8). Le corps (3) recevant le bloc central et la plaque (2) sont en résine synthétique oléfinique. Les éléments constituant une face à dessiner du corps (3) et la plaque (2) sont transparents ou semi-transparents. Le bloc central (5) est en un matériau à base de pâte à papier.
